Best RV Generators

Have a hard time finding a generator that suits the power requirements of your rig? Well, if you need a couple of suggestions, this article could show you in detail some of the finest power generators for recreational vehicles nowadays.

So check out the following models if you want to get your money’s worth.

1. Champion Power Equipment 100263 – Best Of The Best

Champion Power Equipment 100263

  • Power Output: 3,400W (Gasoline) and 3,060W (Propane)
  • Tank Capacity: 1.6 Gallons (Gasoline) and 20 Pounds (Propane)
  • Fuel Type: Gasoline and Propane

Why It’s The Best:

You intend to pick up a propane generator but have concerns about the availability of gas cylinders at your destinations? If that is the case, you should take a close look at Champion Power Equipment 100263. Being engineered to run on gasoline as well as propane, the generator from Champion Power Equipment is the best RV generator in terms of adaptability. Regardless of the locations, finding fuel for Champion Power Equipment 100263 is a piece of cake. Depending on the type of fuel it uses, the output of the CPE power generator changes between 3,400W and 3,060W.

Running at less than 60 decibels, the Champion Power Equipment RV power generator is an all-time favorite of RVers that seek a calm camping atmosphere. At 20 feet, the noise from the generator would be barely audible to the human ears. Featuring integrated handles alongside robust wheels, Champion Power Equipment 100263 could be repositioned in a moment. Moreover, due to the inclusion of the quick-touch panel, it’s possible for people to regulate functions of the CPE generator through centralized controls.

As for the cost, Champion Power Equipment 100263 definitely seems to be a high-priced model at first but its splendid values totally justify the price.

After reviewing a number of generators, I chose this one. It runs as quiet as the Honda at half the cost. It has enough power to run my 30 foot travel trailer including the AC (13,500 BTU). With some instruction from Champion’s tech’s, I was able to connect the generator directly to the trailer’s propane system. I have included a short video clip and pictures. I put a 12 foot hose between the regulator and the flow valve. I put a quick connect on the trailer and on the original regulator. This enables me to run the generator on gasoline, propane bottle and the trailer’s propane system. The generator is light enough for me to lift it into the bed of my truck and it fits under the tonneau cover! These features make this generator the perfect camping generator. I do not have to carry extra fuel! The trailer’s propane system has two 20lb propane bottles. That is enough propane to run for a 3 day weekend in economy mode running only during the campground’s generator hours. My wife was very happy that we now can get the large unpowered camp sites most state parks offer without loosing any of the functions of the trailer.

This generator is also powerful enough to use as a back-up generator for my house. I have installed a 30 amp RV plug next to the sub panel in my garage. In an extended power outage, I will open the main breaker then be able to safely plug it into the house to back feed power to the furnace some lights and the refrigerator. This is a great addition to my house & camping equipment.

Through the catchy status lights on Generac GP2200i, you could tell the conditions of the generator with a glance. The combination of a rugged build in-handle and a lightweight construction lead to top-notch handling characteristics as well.

One interesting thing about GP2200i of Generac is that it possesses an economy mode. If engaged, the economy mode of GP2200i would reduce fuel consumption and extend runtime. As a result, to RVers that prioritize fuel economy, Generac GP2200i is the best RV generator money can buy.

The Generac GP3000i is a great little generator. I almost didn’t buy it because I couldn’t find any reviews. I’m glad I did – It’s quiet, light weight, easy to operate, and powerful enough to run the 13,500 BTU A/C unit in my Airstream. I can’t comment on reliability or durability yet, but Generac has a good reputation so, I’m not worried about that.

This is the second generator I bought this summer. The first was a lower cost open frame generator (NOT a Generac) which leaked oil like crazy and was so loud the campers in Shenandoah National Park applauded when it turned off.

In looking for a replacement, I really wanted something quiet and powerful enough to run the RV A/C. So far the Generac meets all my expectations.

+ Light weight ~ 59lbs. It’s pretty similar to lifting a dumbbell. It can be done with one hand.

+ Super Quiet – is an accurate description. At 20 feet it’s slightly louder than ambient noise.

+ Power – it barely surges when starting the Airstream A/C (2-3 second surge) and then normalized almost instantly. It had no trouble running the A/C and everything else in the trailer concurrently (running the microwave at the same time as the A/C is too much).

+ Easy to start – typically starts in one easy pull.

My only complaint (and this is small) is that I had to buy a RV 30 amp adapter to connect to the Twistlock Outlet. It was ~ $12.

How to Choose the Best Generators for RVs, Travel Trailers, Campers

Of course, buying on impulse is ill-advised as that likely makes you waste money on less than ideal models. Overall, if you wish to make a purchase that you won’t regret, you should keep these issues in mind.

best generators for rv


If you want to get the most out of the appliances on your rig then it’s of utmost importance that you give output some thoughts while assessing power generators.

In the case that you don’t have a lot of things that run on electricity around, you may settle for models with standard outputs.

On the other hand, if you own multiple high-draw devices such as microwaves, air conditioners, fridges and alike, you must prioritize high-output models.

In general, if you nail the output, you and your fellow travelers would have a good time on the road.


To perform as designed, generators need to be kept well-fueled which is why consumption rate is a major consideration.

All in all, if you pick up a power generator that drinks fuel like you drink water, you could have a hard time fueling it. 

So to avoid a potential logistic headache, it’s strongly recommended that RVers choose models with reasonable fuel consumption rates.

A number of generators available for purchase nowadays even feature eco-modes that ought to reduce consumption rates once engaged.  


In use, power generators tend to make some noises but certain models on the market make less noise than the rest.

Hence, if you prefer to have an undisturbed night’s sleep after a long day behind the wheel, you should grab a quiet generator.

It’s also worth noting that various camping grounds for recreational vehicles have regulations regarding the sound levels of generators.

That means if you use a generator that proves way too loud, few locations would welcome you and your RV.   


Like noise, you must pay attention to emission if you wish to buy the best RV generator for your vehicle.

For your well-being, you need to stay away from models that release harmful exhausts into the surroundings during operation.

To properly evaluate the emission of models on your shortlist, it’s widely suggested that you take a close look at customer reviews and see what people have to say.

Many power generators claim to pass all kinds of emission tests but still let out unhealthy fumes so it’s essential that you take precautions.


Since recreational vehicles experience vibrations and bumps from time to time, power generators for RV use need to be well-built to handle the stress.

If you select a flimsy model, it’s going to fall apart in short order and force you to spend money on getting a replacement.

Because of that, RVers should inspect and examine the constructions of generators prior to purchase.

It’s also wise for you to check out aftermarket support from manufacturers: long warranties often indicate sound build qualities.

Fuel Types Of RV Generators

Modern RV-rated power generators usually run on an assortment of fuels with unique characteristics. Therefore, it’s a good idea to get to know the common types before deciding on what model to buy. 

  • Gasoline: Generally speaking, gasoline is unmatched in terms of availability: you would be able to find it everywhere you go. As a result, RVers that travel extensively hold gasoline generators in high esteem since keeping them fueled is a cakewalk. About the shortcomings, gasoline is highly combustible so you need to be careful around it. In addition to that, gasoline possesses a relatively short shelf life compared to other fuel types used by power generators. That means stockpiling gasoline in big volumes is ill-advised.    
  • Diesel: As diesel is less flammable than gasoline, diesel power generators have good safety records. The shelf life of diesel on average is superior to that of gasoline as well. Furthermore, diesel is highly affordable which makes it the ideal choice for budget-minded RVers. For drawbacks, diesel is uncommon in particular regions so if you go with a diesel generator, it may be tough to secure fuel on occasions. Also, once it comes to generators that run on diesel, RVers could only choose from a limited number of models.   
  • Propane: Lasts a long time, burns cleanly and comes in handy canisters, propane is considered to be the best all-around fuel for power generators. Because propane generators reduce carbon emissions in the outdoor environments, they tend to be well-liked by eco-conscious RVers. One disadvantage of propane is that it burns fast: a tank would be used up in the span of 24 hours. Thus, in extended trips, RV enthusiasts that own propane power generators must carry quite a few gas cylinders as fuel    

Inverter Generators Vs. Conventional Generators

The market of power generator for RV indeed features plenty of models but it’s possible to put them into two categories: inverter and conventional.

Unsurprisingly, due to the diversity of preference, RVers have a wide range of opinions about inverter generators vs. conventional generators.

The following key points contain everything you should remember regarding the attributes of the generators.


To put it plainly, inverter power generators produce electricity in three phases (AC – DC – AC) while conventional ones produce electricity in a single phase (AC).

Hence, the sine wave of inverter models is stable which ensures negligible harmonic distortions, a major plus for RVers that bring lots of sensitive electronics.

In the case of conventional generators, the sine wave is kind of messy so harmonic distortions happen now and then.

Needless to say, such distortions could cause permanent damages to delicate components in various devices. 

Efficiency And Capacity

Thanks to the way electricity is produced, the fuel efficiency of inverter power generators is deemed to be top-notch.

As a result, the average inverter models pack small fuel tanks since less fuel is needed to keep them running.

On the other hand, conventional generators boast big tanks because they have an inferior efficiency.

However, the size of the fuel tank affects output: power ratings of standard inverter power generators often stay around 5,000W.

In the case of conventional models, the power ratings may even reach up to 10,000W.


With big fuel tanks, huge engines and vast housings, conventional power generators certainly don’t impress a lot of people if it comes to portability.

RVers could still move conventional models from spot to spot if necessary but that is going to be slightly tedious.

As for inverter generators, the compact profiles ensure that RV enthusiasts would be able to handle them without much hassle.

In fact, many inverter models prove to be light enough to be carried by hands.

Pro Tips to Keeping RV Generators In Top Shape

It’s definitely nice to have the best RV generator on your rig as you head out but aside from using it, you must take good care of it too.

So if you need help with maintenance of generators, check out the pointers down below.

Invest In A Cover/Enclosure

While power generators should be used outdoors, leaving them exposed to the elements is unwise.

All it takes is one drop of water seeping through the outer housing and your generator may experience operational failures.

That is why if you care about the integrity of your generator, it’s strongly recommended that you purchase a  purpose-design generator cover/enclosure.

By putting a cover/enclosure on top of your power generator, you could protect it from an assortment of troubles.

Avoid Depleting The Fuel Tank

For your information, generators produce electricity by constantly rotating the magnetic coils along each other.

So once the power generators run out of fuel, they stop generating electricity but devices continue to draw power from them which demagnetized the coils.

The result is a hefty repair bill that likely ruins the budget plan of RVers.

Thus, it’s of utmost importance that you refrain from depleting the fuel tank of your generator all the way.

Pay attention to the fuel level and if it gets low, refill the generator tank.

Remember To Perform Periodic Inspections

Every now and then, you should take a close look at the power generator of your RV just to see if it needs some work.

Things such as oils, coolants, filters and so on have substantial influences on the performance of generators as a whole.

If you perform periodic inspections, it’s possible to notice potential issues and resolve them before they actually cause damages.

In the opinion of experts and experienced RVers, the ideal interval between inspections is 1 month.

Let The Generators Run Often

To stay in working order, machines need to be turned on from time to time and the same applies to power generators of recreational vehicles.

If you allow the generator on your rig to collect dust for too long then it may refuse to start-up in times of need.

So as to ensure that your generator could power your RV, it’s essential that you let it run a minimum of 30 minutes every 3 months.

In addition, since it’s ill-advised to leave fuel in the tank indefinitely, it’s a good idea to take out aged fuel during maintenance runs in off-seasons.

FAQs About RV Generators

How many watts does it take to run an RV air conditioner?

Typical air conditioners have two wattage ratings: one for start-up and one for running. To power an A/C and keep it running, you have to get a power generator that matches its ratings. Keep in mind that as cooling power (usually measured in BTU) grows, the rating increases.

For example, your RV currently packs a 7,000-BTU air conditioner that features a start-up rating of 1,800W and a running rating of 650W. To keep that A/C running, you need to pick up a generator with a power rating of 2,000W and above. 

How long can you run a generator continuously?

Different models have different limits so you should take a glance at the owner’s manual of your power generator to learn its maximum runtime. Quite a few generators for recreational vehicles could work overnight (8 hours) and some may run for half a day (12 hours).  

How to make an RV generator quieter?

Your generator is kind of loud and you wish to give your ears a break? If that is the case, you must consider fitting some sound mufflers to your generator. Assuming that the installation proceeds smoothly, the mufflers would reduce the overall noise level noticeably. Putting a noise reduction box on top of the generator is also a superb option.

How do you connect a generator to an RV?

The procedures change from case to case which is why RVers have to rely on the owner’s manual while hooking generator to recreational vehicles. Follow instructions in the manual and you should be able to finish setting up your power generator without much difficulty.   

What size generator do I need for my RV?

To determine the ideal size of generator, it’s widely suggested that you think about the interior of your rig. Space is a luxury on recreational vehicles, therefore, you need to be thorough here. Having the best RV generator is pointless if you fail to fit it in your rig.
