5th Wheel To Gooseneck Adapter Basics
What is a hitch?
A hitch is a connection system that attaches a travel trailer or a 5th wheel trailer to a towing truck. There are different hitches designed for different circumstances, and your chosen hitch would greatly affect your towing experience, including the turning radius or how the trailer follows the towing vehicle when turning, how heavy of a load your car can tow and how well the trailer’s weight is distributed.
Therefore, if you are a first-time camper, you should understand the pros and cons of each type of trailer hitch before installing one on your truck. Once there’s a mismatch between your installed system and what’s on the trailer you want to tow, you will need to make a few decisions as outlined below.
Although there are more types of hitches for towing, the gooseneck and 5th wheel hitches are the two trailer hitches particularly used for hauling heavy loads, with the gooseneck hitch allowing for heavier towing jobs between the two.
A 5th wheel trailer would typically come with a 5th wheel kingpin for connecting to a corresponding 5th wheel hitching system on your towing truck. But in the case that you have a gooseneck hitch system already installed on your truck, but need to tow a 5th wheel, you have two options.
One is to remove the existing hitching system on your truck and put in a 5th wheel system instead. This is recommended by experts if you prioritize getting a smooth, more stable ride. The second is to use a 5th wheel to gooseneck adapter, which would allow you to connect the gooseneck hitching system on your pickup to the 5th wheel kingpin on the 5th wheel trailer.
Put simply, a 5th wheel adapter allows a gooseneck hitch to tow 5th wheel trailers, as long as there is sufficient weight capacity and the correct adapter is installed.
There are different types of 5th wheel to gooseneck adapters which work a bit differently, but in general, an adapter comes with a shank to drop into the gooseneck ball hole on your truck’s hitching system and an adapter plate that can be installed into the gooseneck hitch, providing a set of industry-standard 5th wheel base rails to accept a 5th wheel hitch.

Gooseneck vs 5th wheel
While a “gooseneck travel trailer” comes with a coupler for gooseneck hitching, a 5th wheel trailer typically comes with a king pin plate already mounted to the front of the trailer for 5th wheel hitching. A king pin is a round steel shaft, which allows the fifth wheel hitch on the truck to clamp around it.
In general, the gooseneck trailers are more typically used for really heavy towing jobs and industrial trailers due to its capacity for a heavier load. If you want to transport heavy and bulky cargo, then a gooseneck hitch is advisable.
Meanwhile, fifth wheel trailers are more common for recreational purposes. If you plan on carrying passengers, then it is better to go for a fifth wheel, which is best towed using a 5th wheel hitching system. According to experts, towing a 5th wheel trailer using a 5th wheel hitch on your pickup will generally offer a smoother towing experience. You can further improve this with an air-ride pin box, also called an ungraded king pin receiver to help reduce road shock from the tow vehicle and dampen the resulting noises.
How 5th Wheel to Gooseneck Adapters Come Into Play
That said, if your pick up truck already has a gooseneck hitching system installed for regular heavy towing jobs and you just bought a trailer that comes with the 5th wheel king pin, what should you do?
You don’t have to remove the existing gooseneck hitching system on your vehicle to replace it with a new 5th wheel system. A 5th wheel to gooseneck adapter will allow you to connect the trailer’s 5th wheel king pin to the gooseneck ball on your pickup.
Such an adapter allows you versatility and flexibility: you can either perform your regular heavy towing jobs or tow a gooseneck travel trailer using just the existing gooseneck hitch alone, or tow a 5th wheel trailer using the adapter.
That said, since fifth wheel campers are more common for recreational purposes, if you’re purchasing a towable RV for traveling on the open road, you should install a 5th wheel hitching system on your truck. If you are sure that you’d only be towing a 5th wheel at all times in the future, having a 5th wheel hitch installed on your truck would also mean you’d need to make less considerations regarding your towing setup.
For instance, when you use an adapter, the adapter needs to be of the appropriate height, which must absolutely fit snugly between the top of the gooseneck ball and the bottom of the 5th wheel king pin plate for a secure connection. Another thing that you must take into careful consideration is that you must double or triple check that the adapter wouldn’t stretch the frames of the fifth wheel over its limit. Below are the advantages and disadvantages of using a 5th wheel to gooseneck adapter to tow a fifth wheel trailer. Do consider your towing needs carefully to better decide whether to use an adapter or install a new 5th wheel hitch on your towing vehicle.
5th Wheel to Gooseneck Adapter Pros & Cons
Pros:
- Flexibility With Different Towing Setups For Different Jobs: If you need a gooseneck hitch on your truck for regular heavy towing jobs, like towing lumber or construction materials, so you might not want to remove it to put a 5th wheel hitch in place just to tow your 5th wheel on occasional camping trips. Having the right 5th wheel to gooseneck adapter in place would allow you great versatility, so that you can use different setups for not just doing your regular towing and towing a fifth wheel trailer, but also for towing a gooseneck travel trailer. This is especially handy if you do not own but rent an RV for camping, and might want the flexibility of towing different trailers each time.
- An adapter for every needs: Depending on your needs, you can get an adapter with adjustable heights, a secure connection for a more permanent solution or a flexible connection that facilitates frequent switching between trailer types, or one that doesn’t take up space in your truck bed for other hauling purposes.
- Easy To Install and Operate: Installation of an adapter and hitching can be done simply. All the different types of 5th wheel to gooseneck adapters have straightforward mechanisms. A common type typically features a removable ball that is very lightweight and can come directly down to the ball hole of the gooseneck hitch for easy operation. Or the adapter can mount to the gooseneck ball in your truck bed, or mounts around the fifth-wheel king pin on your trailer, or replaces the king pin entirely.
Cons:
- Some Adapter Might Put Extra Stress On Trailer’s Frame: The extra torque caused by certain types and models of gooseneck adapter may stretch the frame of your fifth wheel trailer beyond its limits and may damage it. That only means you need to consider different options to find the one that offers the right balance of pros and cons for your needs, as there are also 5th wheel to gooseneck adapters that will directly couple your trailer to the ball and will not put any extra stress on the frame.
- Can Void Your Trailer’s Warranty: Keep in mind that some RV makers have a clear-cut rule that if the trailer is damaged because of a hitch adapter, the original manufacturer’s warranty, so be prepared for the risks.
- Might Not Come With a Warranty: Although the best 5th wheel to gooseneck adapters on the market often come with some kind of warranty, this is not true in all cases. Some manufacturers lack the adequate testing, thus they do not offer a warranty with their adapter. Do check this when comparing different models. Often, as with anything, a solid warranty usually is proof that the model is well designed with excellent construction quality, and can be expected to be more durable.
Types of 5th Wheel To Gooseneck Adapters
Adapters that Slides in the Ball Hole of the Gooseneck Hitch
These adapters feature a lightweight removable ball that can slide directly down to the ball hole of the gooseneck hitch. Because this adapter replaces the king pin on your trailer, you won’t need to measure for height. All in all, this type of adapter is extremely versatile, very easy to install, hitch up and remove.
This type of adapter offers the most adaptability for different jobs. It’s the most suitable if you frequently need to switch between towing a 5th wheel trailer, a gooseneck travel trailer or other towing jobs while driving the same towing truck. In addition, it can be easily removed when you need to haul cargo in the truck bed,and it doesn’t require any modification to the trailer.
One thing to note though, these adapters are made to fit specific pin boxes, so you must check your make and model by looking for a plate or sticker with this specification.
Adapters that Replaces the trailer Pin Box
These adapters replace the pin box on your trailer entirely, thus allowing for the most secure connection and is meant to be more of a permanent solution, without the adaptability of the first type. The major advantage is that the adapter will leave your truck bed open for other uses, and there’s no additional stress on either the trailer frame or the hitch. Also, you won’t need to measure for height, since the adapter will replace your trailer’s king pin.
Note that as a more permanent hitching solution, they are made to fit specific pin boxes though, so you’ll have to check which make and model you have on a plate or sticker on your unit.
Adapters that Attach to the Fifth-Wheel Trailer King Plate
Another type of 5th wheel to gooseneck adapter takes the form of a tube that mounts around the king pin on your trailer and attaches to the entire fifth wheel plate at one end, and at the other end attaches to the gooseneck ball in your truck bed. This setup does not require the removal of the king pin and pin box.
The advantage of this type of adapter is that since it does not pull on the king pin but instead is mounted to the entire fifth wheel plate that the kingpin is attached to, the setup strengthens the kingpin box as well as allowing for an even weight distribution across the entire base plate.
As for downsides, this type of 5th wheel to gooseneck adapters cannot be used on all 5th wheel trailers. You’d need to check with your manufacturer. Plus, this type of adapter is very heavy, which makes installation less straightforward and might require some assistants. And since it’s extra heavy, it might cause stress on the trailer frame and hitch, thus you will need to check in respect to your trailer’s limit to avoid damages
Some products in this category are not recommended by the manufacturers to be used with pin boxes over a certain length, so do check for maximum recommended pin box length. Another consideration is that these adapters need to be of the correct height to allow for level and safe towing. In this regard, you can get an adapter with adjustable height instead of a fixed height.
Adapters that Attach to a Gooseneck Ball in the Truck Bed
These adapters are the most lightweight options. They mount to the underbed gooseneck ball in your truck bed and allow for adjustable hitch height. The advantage of this setup is that the higher attachment point between your truck’s hitch and your fifth wheel trailer means less stress on the trailer’s frame and pin box, thus a lower chance of damaging the frame.
How To Determine The Required Height of The Adapter
To measure the height of the adapter you will need, you need to take some precise measurements. First, put your truck into position as if you were hooking up your trailer and make sure both vehicles are level. Then measure from the king pin plate down to the top of the gooseneck ball on your truck bed. This number will be the required adapter height. Do note that for safe towing, you should leave about five or six inches of clearance between the side rails of your truck and the overhang of the trailer.
The Best 5th Wheel To Gooseneck Adapters
1. Eaz-Lift Gooseneck Adapter 15 Inch Camco Gooseneck Adapter – For heavy towing

In addition, some customers complain the installation process is not as straightforward as it should be, due to the included nuts and wrench not quite fitting together, which means you might need to use your own toolkit to complete the process.
2. T Built Gooseneck Adapter – Excellent remote release
If you’re one who is always wary of the potential danger when disengaging your trailer from your tow vehicle, then you should really consider the T Built Gooseneck Adapter.

The cast steel construction makes it extra durable, the kit comes with three heavy-duty fasteners, and the rust-proof guarantee by the manufacturer speaks volume about the durability and construction quality of this model.
As for the few downsides, first is the lack of sufficient clearance in the case that you have a newer camper and need more height, despite it being adjustable. The lack of a remote release might not necessarily be the deal breaker, but considering the fact that this adapter is very heavy, you might want the remote release feature so that you won’t have to get close to what might potentially be a source of tremendous force.

Another downside though, is that each time you unhook your trailer, the large airbag will deflate, and you’ll have to re-inflate it.
5th Wheel To Gooseneck Adapters: Buying Criteria
Type
Gooseneck to fifth wheel adapters are available in three major types with different methods for installation and mounting. All in all, the best one for you depends on your towing needs, such as whether you frequently alternate between towing heavy loads for work and towing an RV on holidays, or if you want a more permanent solution.
One type replaces the kingpin on your trailer and slides down to the ball hole of the gooseneck hitch. This type of adapter is very easy to install, hitch up and remove, and is extremely adaptable for towing different types of trailers and different towing jobs.
Another type replaces the pin box on your trailer entirely, thus allowing for the most secure connection. There’s no additional stress on either the trailer frame or the hitch, and your truck bed is open for other uses.
Another type of 5th wheel to gooseneck adapter takes the form of a tube that can be bolted around the kingpin and over the kingpin lube plate on your trailer. This type is very heavy and thus might cause stress on the trailer frame and hitch. But on the upside, it allows for an even weight distribution and strengthens the kingpin box.
Size
After deciding on the type of adapter, you’ll need to do some precise measuring, although you can inevitably do less if you decide on an adapter that straight up replaces the trailer’s pin box entirely. The measurement will help you filter down the most suitable adapter for your vehicles.
It’s crucial that we stress again on the precision of the measurements. If the measurements are not correct and dead-on, even a small error could lead to major mechanical headaches when installing the adapter. It could also result in your trailer not riding level and reduce overall ride comfort when towing.
The first required measurement is the exact distance between the front of the gooseneck’s ball and the bottom of the pin box. Instead of measuring from the top of the gooseneck ball to the kingpin plate, a common mistake many folks make is measuring the distance from the truck bed to the kingpin plate.
This is because the height of the adapter is not the total height of the adapter hardware itself. It measures how much higher the trailer is lifted from the top of the ball, or from inside the hole on the bottom of the adapter to the top of the adapter. If you’re not convinced, take a tape measure to the outside of the adapter. You would get something larger than its rating.
The measurement typically comes out somewhere between 11 and 17 inches for most trailers these days. Most 5th wheel to gooseneck adapters come in 12-inches, 15-inches or 17-inches. Choose the height rating closest to your measurements, and go larger, not smaller. For instance, if the measurement is 11 inches, then the correct adapter should be 12 inches. If it’s 13 to 14 inches, use a 15-inch adapter, and if it’s 15- to 16 inches, you’ll need a 17-inch adapter.
Maximum Towing Capacity
Every 5th wheel to gooseneck adapter has a towing capacity. For instance, a model rated at 20,000 lbs towing capacity would allow you to tow this much. Don’t exceed your truck’s Gross Vehicle Weight Rating (GVWR), which limits the amount of cargo weight inside, including the driver plus passengers, and the weight of anything it tows behind. And know your towing needs so that you choose an adapter that has adequate towing capacity, if you prioritize safe towing.
Maximum Tongue Weight
Tongue weight measures the weight that a fully loaded trailer exerts downward on the hitch ball of the tow vehicle. It also determines the total weight that can be exerted by the trailer tongue. For safe towing, this should be between 10 to 15 percent of gross trailer weight. Too much tongue weight will cause the trailer to sway from side to side.
A 5th wheel to gooseneck adapter comes with its own tongue weight or pin weight capacity, which is the maximum downward force the adapter can handle. The handy tip for towing is to try to distribute more of the gross vehicle weight in the front of the trailer for a more stable ride. With a well-distributed weight and the correct tongue weight, your vehicle and your trailer will be kept in a straight line while traveling on the road.
Handy Features
After considering the crucial criteria above, to further shortlist your best options, you might want to consider special features that allow for safer and better ride comfort, or security features once you are unhitched.
Safety: Safety features like robust tow chains and hasps in the cap can allow for safer towing on the open road. A remote release feature is also helpful in keeping you and others out of harm’s way while unhitching, as it lets you disengage the trailer from the adapter without having to get too close to what could be a potentially large amount of force. Most remote releases are made from a braided steel cable with a sturdy handle on the end, which you simply need to pull to disconnect the hitch adapter and the trailer.
Increased Clearance: If you need a little extra clearance between the fifth-wheel-trailer overhang and the back of the truck cab, look for a 5th wheel to gooseneck adapter with an offset. This type of adapter can also provide a bit more clearance between the back of the truck and the trailer. An important thing to note if you opt for this type of adapter is that if you own a short-bed pickup, you will have difficulty executing a 90-degree turn. For safety, you will need either a sliding fifth wheel hitch or a fixed fifth wheel hitch and a sidewinder pin box.
Ride comfort: The highest rated adapters for the adventurous campers typically offer some type of cushioning for a smoother, more stabilized ride. Not only does it make for better ride comfort, but it can also reduce road noises. This is particularly a desirable feature if you tend to travel on rough terrains and long drives between campsites.
The best adapters typically offer either mechanical or pneumatic cushioning. They employ different methods, but they both work to reduce the shocks and vibrations that’s unavoidable when you tow a bulky, heavy trailer on rough terrains.
The cushioning feature is important in the way that it also minimizes long-term wear and tear on the tow vehicle, which is always nice, but especially so if you tend to travel off the beaten path, or if you have an older truck and it already sustains a bit of structural rust.
Adjustability: If you only plan on towing the same fifth-wheel trailer in the foreseeable future, then obviously a hitch adapter with additional height adjustability feature might not matter as much. However, if you rent different trailers each time for your trip, or if you need to tow different fifth-wheel trailers for work, such as for towing livestock or equipment or construction materials, you’d appreciate extra versatility. Even if you’re only towing a trailer for camping, having more adaptability does open up more travel opportunities.
Security: Security features like couplers that lock with a trailer padlock or other ways to lock people out from hooking up to the pin box on the trailer would always come in handy. No one wants to have someone tampering with their rig when they’re away, especially when the trailer is parked unattended for extended periods.
Durability
The highest-rated trailer hitching systems as well as 5th wheel to gooseneck hitches are often made from solid steel. Since they are very rigid and durable, they are less likely to bend for crack under tremendous amounts of pressure. In addition, ones made from stainless steel are less likely to rust, which would be highly desirable considering the fact that the adapter and your hitching system will be exposed to the unforgiving outdoors elements. Rust would affect the integrity and durability of your expensive trailer hitch adapter.
Price
Most fifth wheel to gooseneck adapters on the market cost about $400 to $500. You might think this is expensive, but remember that they are built out of at least 40 lbs of solid steel, and you must get a decent one as such an adapter makes up the critical connection between your tow vehicle and the trailer. You need the best 5th wheel to gooseneck adapters for safe and stable towing, so that big price tag is justified.
There are some models costing less than $400, but if you value safety and especially if you need to tow a heavy load, it’s not recommended that you go for anything costing less than $350. $350 should be your floor, since anything cheaper than the normal range would usually have some sort of short cut taken in their design, material, or engineering.
On the other end of the spectrum, you might see other adapters that cost north of $700, which might not be necessary considering your towing needs. Other than price, carefully check all the important specifications to make sure you get the right adapter for your vehicle and towing needs.
Gooseneck Hitch vs 5th Wheel Hitch
Gooseneck hitch and 5th wheel hitch are two different hitches, but many folks think they are the same since they do share some similarities. They are both preferred by veteran RV owners for heavier towing jobs and a smoother ride, while beginners tend to opt for other hitches like the common bumper pull hitch, which are made to tow lighter weights, but are cheaper and simpler.
Gooseneck Hitch
A gooseneck hitch is mounted in the bed of the towing vehicle instead of the rear bumper like the bumper pull hitch commonly used to tow lighter RVs. The system features a ball mount at the same level with the bed of the trailer that attaches to a coupler on the trailer.
The first major advantage of a gooseneck hitch over other types is that it allows for heavier towing jobs. Since the attachment point is over the rear axle of your truck instead of at the back of the frame, the majority of the trailer’s weight rests directly on the rear axle, which is the component that turns the rear wheels.
This very distribution of weight allows you to tow more weight. The second major advantage of using a gooseneck hitch is safer, more stable towing experience, since this setup minimizes swaying.
Another plus is they have a tighter turn radius, so you can make sharper turns and better maneuver the trailer while traveling off-road or parking in tighter spaces. This feature is extremely important for campers who prefer to travel off the beaten path.
Compared to the other hitches that attach to a truck’s rear end, the main disadvantages of gooseneck trailers are its size, weight and a bit more complex mechanism. That said, it’s still straightforward to install and operate.
Gooseneck hitches are bulkier and heavier, so you must own a pickup or a tractor if you want to install one of these. They also require a special hitching system installed in the bed of the tow vehicle, including a gooseneck trailer ball.
Since gooseneck hitches are less common than other low-capacity hitches and are more commonly used by veteran trailer owners for heavy towing, most trucks won’t likely have the gooseneck hitching system in place.
Fifth Wheel Hitch
While a gooseneck hitch uses a ball that engages with a coupler on the trailer, a 5th wheel hitch uses a king pin on the trailer to attach to a U-shaped king pin receiver on the bed of the towing vehicle.
Similar to a gooseneck hitch, a 5th wheel hitch is also designed for heavier towing jobs than what the common bumper pull hitch can enable. It’s also mounted in the bed of the towing vehicle.
In addition, with this hitch, the trailer’s weight also presses down almost directly over the rear axle of your pickup, thereby allowing it to tow more weight. Therefore, gooseneck hitches and 5th wheel hitches are similar in many ways, including effective weight distribution, optimal towing capacity as well as a smoother, more stable towing experience.

How To Install a 5th Wheel To Gooseneck Adapter
Before starting to hook up your fifth wheel to gooseneck adapter, the first thing you’ll need to check is the length of your kingpin box. If it is over 30 inches long, the extra extension of your kingpin box you would most likely need some strengthening for safe towing since the heavy adapter will put additional stress on it. You might need gussets or other mediums to provide extra support. While open kingpin boxes are more common, you might have a closed unit, so follow the steps below as they involve a bit different installation steps.
If you have an open kingpin box:
- The base plate of the adapter hitch usually has a slightly longer side, say 10 inches and 12 inches.Generally the shorter side should face forward, which should work best with most 5th wheel trailer pin boxes.
- If there’s a lube plate around the kingpin, you need to remove it so the adapter can attach securely to the kingpin box. To allow the adapter to bolt to the kingpin box, you’ll need to drill 4 holes into the kingpin box. For precision, you should dry fit the adapter hitch over the kingpin to mark the location of the holes with a Sharpie marker.
- Check your product’s instructions on how to measure the placement of the four holes. You can draw it out on a poster board and use that to center punch the start points. Do not drill all four holes in one go.
- Drill the holes into the fifth wheel pin box. Make sure they are large enough to receive the bolts provided in the kit. A general rule in drilling holes on anything is, after drilling the first hole, attach the hitch with one bolt first to double check the location of the other holes before drilling. You can just leave the hitch in place on your trailer and drill the remaining three holes.
If you have a closed kingpin box as opposed to an open kingpin box, you will need to follow the extra steps as follows:
- If you cannot access the inside of the kingpin box, you will need to tighten the bolts through the top of the kingpin plate. You can use a hole saw to drill these access holes. You must check the placement of the attachment drill holes first before deciding where to drill the access holes. They could be located on the side or top depending on your model.
- Before you drill the access holes, check the size of your tools first to make sure you can get them through the holes. A 1 and ¾” hole saw should be big enough to allow you to get a wrench or socket wrench through the hole to tighten the bolts.
- Now you’re done. Just use the provided caps to plug the holes from the hole saw.
No matter how you installed your adapter, for safety reasons, you must regularly inspect the bolts, the adapter, the latch and the kingpin box after the first 50 miles or so, then again after 100 miles, after 200 miles and so on to make sure your installation was proper and secure.
Frequently Asked Questions
1. Can you hook a gooseneck to a fifth wheel?
Yes you can. If you already have a gooseneck hitch installed on your truck but need to tow a 5th wheel trailer, you can use a 5th wheel to gooseneck adapter, as long as there is sufficient weight capacity and the correct adapter is installed.
You don’t have to remove the existing gooseneck hitching system on your vehicle to replace it with a new 5th wheel system. A 5th wheel to gooseneck adapter will allow you to connect the trailer’s 5th wheel king pin to the gooseneck ball on your pickup. This type of adapter comes with a shank to drop into the gooseneck ball hole on your truck’s hitching system and an adapter plate that can be installed into the gooseneck hitch, providing a set of industry-standard 5th wheel base rails to accept a 5th wheel hitch.
2. Are 5th wheel to gooseneck adapters safe?
Yes, despite the fact that most types of 5th wheel to gooseneck adapters cause some stress on the trailer’s frame and the hitch, these adapters are generally safe. This is because most adapters are typically designed with a very large base plate and are screwed to the underframe of your tow vehicle.
Most models also feature secure locking mechanisms that enable secure connection to better keep your trailer in place while you’re traveling on rough terrains. Also, you can expect most models on the market that allow for heavy towing jobs of up to 35,000 lbs or greater.
That said, for safe towing, you need the correct adapter installed in regards to height and weight ratings. Your trailer must come in below the adapter’s maximum weight rating.
3. How much is an adapter to go from a 5th wheel to a gooseneck?
The price range of a 5th wheel to gooseneck adapter is not very broad, with most models on the market ranging from $400 to $500, depending on the brand and features.
There are cheaper models, but they typically would not offer as much durability, a secure connection and other handy features, such as cushioning for shock absorption. There are more expensive models too, but anything within this price range should be adequate. The rest depends on how you pick the most suitable model for your towing needs.
4. What are the best trailer hitch adapter brand?
There are a handful of manufacturers for trailer hitch adapters, including CURT, Andersen Hitches, Reese Towpower, T Built, Weigh Safe, Connor, Towever, and BulletProof Hitches. But particularly for 5th wheel to gooseneck adapters, brands with products that receive raving reviews by buyers and positive opinions by experts would be CURT, Andersen Hitches, Reese Towpower, T Built, particularly CURT, which often has more than one product covered by many reviews on the Internet.
5. Does a fifth wheel hitch increase towing capacity?
It’s not possible to increase the towing capacity of your tractor or truck. The only way is to upgrade or re-engineer it, including upgrading the suspension, replacing the axles, installing a bigger radiator, using a programmer and upgrading the braking system.
Your truck has a Gross Vehicle Weight Rating (GVWR) that limits the amount of cargo weight inside, including the driver plus passengers, and the weight of anything it tows behind. If the desired amount of load does not exceed the GVWR, using a 5th wheel hitch can improve your hitch load limit, which is the weight allowed by the trailer hitch.
If you can’t re-engineer your tow vehicle, never try to exceed its towing capacity because it’s dangerous. Towing too heavy a load reduces your braking and steering control, which is extra troublesome if you travel off the beaten path on rougher terrains. While your towing capacity cannot be changed, towing can only be improved with weight distribution. A useful tip for towing is to try putting 60% of the load on the front half of the trailer to improve stability and control at highway speeds.
6. Does a gooseneck trailer increase towing capacity?
Gooseneck trailers are primarily for industrial use, so they are often longer, wider, and heavier, all the while without destabilizing the tow vehicle. That means a gooseneck trailer with a gooseneck hitch would allow you to tow much more than a bumper pull. If you need something for hauling more weight, then get a gooseneck trailer and install a gooseneck hitch on your truck.
7. How much does it cost to put a gooseneck hitch in a truck?
If you want some high capacity hitch for real heavy-duty towing, be prepared to pay around $800 to $2800 on average to have a new gooseneck trailer hitch installed on your pickup.
8. Where should a gooseneck hitch be placed?
The gooseneck ball hole should be located right in the middle of the wheel wells and above or slightly forward of the rear truck axle. You will need to measure precisely where the ball hole will need to be cut in your truck bed.
