Though it’s not exactly pleasant, processing wastes remains critical in RVing: you would be unable to enjoy your outdoor experience if the waste tank of your rig is overflowing. 

In the ideal scenario, you simply have to empty all the contents inside your waste tank into a dumping station. 

That being said, from time to time, directly draining the waste tank using dumping stations is impossible due to certain reasons (rough terrains, short hoses, …). As a result, before hitting the road, you should consider putting a portable waste tank for RV on your rig.

With a portable waste tank by your side, you could quickly and effortlessly dispose of the waste of your RV. 

Still, if you lack knowledge about the models on the market, you likely have a hard time determining which one is the best RV portable waste tank for your rig.

Top-Rated RV Portable Waste Holding Tanks

There is really no such thing as the best RV portable waste tank for everyone. Nevertheless, in the case that you wish to get your money’s worth, keep in mind the models down below.

1. Barker 27844 – Best Of The Best

Why This Is The Best:

Constructed using blow-molded polyethylene, zinc-plated steel and aluminum, Barker 27844 is light compared to classic waste holding tanks and its durability is impressive too. From elements to vibrations, the RV portable waste tank of Barker would handle virtually anything. In addition, boasting two large rear wheels and a double wheel-swivel at the front, 27844 also possesses top-notch mobility. As a result, with 27844 of Barker onboard, you should have an easy time dumping the wastes of your rig in a wide range of terrains.

Since 27844 packs a tank indicator, telling when it needs to be emptied is a cakewalk. The waste holding tank made by Barker comes with a conventional waste valve, hence, there is no need to lift it up while draining it. Upon purchase, Barker 27844 is accompanied by hose clamps, adapters, caps and more so it could be put to use immediately. Needless to say, owners of recreational vehicles that need a portable waste tank in a hurry hold 27844 in high esteem. 

About post-sale support, Barker backs its waste holding tank with a two-year warranty. That means if your 27844 fails due to defects in the warranty period, Barker would willingly offer you a free replacement. 

If you have been camping and see the red light go to F, you know the feeling of letting everyone know no more using the bathroom. Debating whether to hook up and go dump or use mother nature. This will save a lot of headache. This tote is big enough for most campers to dump the whole tank black or gray. No worrying about trying to cut it off in the middle or over filling. Have never had a spill with this loading or unloading. I would buy this product again without question.

  • Inexpensive 
  • Outstanding handling
  • Maintenance is child’s play 


  • A couple of parts should be strengthened 
  • Customer service still leaves something to be desired 

2. Camco 39002 – Editor’s Choice 

Why It’s An Editor’s Choice: 

Owing to a combination of heavy-duty wheels and oversized handle, 39002 of Camco could be easily maneuvered through various obstacles. Because of that, 39002 tends to be well-received by people that want to pull their waste tanks to the dumping stations as quickly as possible. Moreover, the low placement of the drain hole on the Camco tank ensures that the wastes would be removed completely. The smooth interior of Camco 39002 superbly tackles the issue of trapped odors so enthusiasts of RVing don’t have to put up with lingering smells. 

With a leakproof body made from UV-stabilized HDPE, the RV portable waste tank of Camco holds together well in regular use. Interestingly, 39002 contains a built-in rinser that allows owners of recreational vehicles to flush it quickly and thoroughly. Thus, once it comes to ease of maintenance, Camco 39002 outmatches the average waste holding tanks for RV on the market. Besides that, as the tank from Camco carries an integrated ladder hook, RVers have the option of mounting to the ladder and save interior space. 

Available at a price that ordinary RVing enthusiasts could accept, 39002 of Camco is pretty affordable. As proof of confidence, Camco over everyone that picks up its portable septic tank for campers a two-year warranty. 

Good quality build. Does the job very well and give it 5 stars. The large wheels make travel over bark, gravel, and dirt easy. We have a small step that it also has to roll over and does it fine, albeit heavy when full.

There are a couple of things to know before buying that may affect your decision.

1. Due to the size it sits high. Depending on your clearance under your trailer it may cause an issue. For example for my purposes using this on a 2 acre parcel, I had to dig out a little so this would sit a couple inches lower. I do not consider it a fault of the product so no stars removed. But an important consideration for your application.

2. There is a metal tow handle. While moving by hand I use that on the front so that its extended. It is not a permanent attachment but fits into place and can move around. Using by hand without an extension was more difficult. A strap or other means to extend the front makes movement easier….think of pulling a roll on luggage onto a plane. The longer the handle the less likely your legs will hit it.

Hope these two things help in your decision making. Please mark helpful if you found it useful. Thanks

I mean, if you want to move poop from your camper to the dump site in style, this is it. I could have towed it behind my truck, but I wanted to walk it to the dump site myself. The stylish look, and ease makes it look good. Wheels are big, and the mouth on the tank is big; you know for the wife’s turds and bundled up toilet paper. Great buy, and would buy again.

3. Thetford SmartTote 2 (40503) – Editor’s Choice

Why It’s An Editor’s Choice: 

Dependable and reliable, Thetford SmartTote 2 (40503) is a solid tank that never lets its owners down in the course of operation. Equipped with an innovative AutoStop level gauge, the tank from Thetford prevents overflowing and improves venting at the same time. Also, SmartTote 2 (40503) incorporates a handy retractable hose that is secured by a retainer strap so its storage is a breeze. Unsurprisingly, Thetford SmartTote 2 (40503) is sought after by enthusiasts of RVing that own small rigs and have little space to spare. 

Employing resilient heavy-duty rubber wheels and high-strength bearings, the Thetford waste tank navigates rough grounds with relative ease. In the case that you travel around the year and need something that could take on variable terrains, SmartTote 2 (40503) is going to suit you well. Thanks to the sublime structural integrity, Thetford SmartTote 2 (40503) remains uncompromised as it’s exposed to heat, moisture, sunlight, … over time. So if you grab the tank of Thetford, it would be years before you have to consider getting another tank. 

SmartTote 2 (40503) on its own works nicely but depending on current demands, RVers may purchase several extra accessories including tow strap, elbow nozzle and drip cap. Hence, it’s simple for RVing enthusiasts to adapt the RV portable waste tank made by Thetford to particular arrangements. 

The 2 wheeled SmartTote2 is a straightforward 35 gallon portable waste tank for RV’s. Make sure you tighten the hose connections prior to using as they are quite loose as shipped and would leak if not tightened. I decided that this was the least cost tank (over the 4 wheeled version) provided I could lift the tow end. I use a trailer dolly and some 3,500# Mule Tape as a handle for this purpose. I read numerous reviews of the optional rubber tow strap breaking and I already have an ample supply of the Mule Tape on hand. The trailer dolly makes lifting the tank very easy and allows easy rolling even through grass.

How To Choose The Best RV Portable Waste Tank

People nowadays have countless ideas about what could be called the best RV portable waste tank but to make a wise investment, it’s suggested that you remember these criteria

portable septic tank for campers


In layman’s terms, the capacity of a particular portable sewer tank for RV determines the amount of waste that it’s capable of containing. 

As the capacity of the tank you own affects the time and effort that go into waste disposal, you need to pay it special attention.

In the case that you travel on your own and your trips tend to be short, it’s fine to settle for a standard tank. 

On the other hand, if you like extended outings with a huge party, you should stick to high capacity models.


Space is a luxury on recreational vehicles, hence, it’s essential that you think about dimension prior to putting a waste tank on your rig. 

The last thing you want to spend your money on is a tank that your RV is unable to accommodate. So in order to ensure that you pick up an appropriate tank, you need to take your RV into account. 

It’s worth noting that depending on the models, today’s portable RV septic tanks could be stored inside as well as outside recreational vehicles.  


In use, RV waste tanks would be exposed to a wide range of outdoor elements. 

Additionally, as RVers move from place to place, the tanks undoubtedly experience considerable vibration which makes ruggedness an important concern. 

Usually, it’s possible to tell how well a model holds together by taking a close look at its material. Waste tanks that incorporate high-tier materials should outlast ones made from low-grade materials.


Processing wastes on RV is already tough as it is so you don’t need a portable waste tank that gives you extra problems while you bring it into position. 

To avoid ending up with a troublesome tank, you should thoroughly assess the handling characteristics of models on the market. 

Besides making direct evaluations, it’s a good idea to go through reviews written by fellow owners of recreational vehicles. 

That is going to help you decide the suitability of certain portable waste tanks for RV and shorten your shortlist.


In general, there is no need to spend big bucks to own a decent portable waste tank for travel trailers. That being said, creating a sound shopping budget is still the key to getting the best RV portable waste tank

It’s strongly recommended that you compile a list of desired capabilities, identify models that match that list and proceed to note down their prices. 

With the prices as references, you could come up with a budget that is neither too low nor too high.

Types Of Waste Holding Tanks For RV

Though the number of portable black water tanks for RVs indeed appear overwhelming, it’s possible to split models on the market into four types: polyethylene, polypropylene, grey and black. 

  • Polyethylene Waste Tanks: Being both versatile and long-lasting, polyethylene waste tanks adapt pretty well to an assortment of conditions. Models of the type excel at keeping odors of the wastes from escaping too, thus, they often earn positive remarks from RVers around the globe.
  • Polypropylene Waste Tanks: With rather light bodies, polypropylene waste tanks routinely outmatch their polyethylene counterparts once it comes to mobility. Moreover, models of the type have superb resistances against elements in the outdoors so they last long in regular use.
  • Grey Waste Tanks: To put it plainly, grey waste tanks are used to store things that go down the sinks, showers and drains of RV. Models of the type could be emptied of their contents with a lot of methods. 
  • Black Waste Tanks: Designed to accommodate wastes coming straight from toilets, black waste tanks must be drained at appropriate locations. As accumulated wastes may lead to blockages once water moves away, models of the type should be used with chemicals that break up solid matters.

The brand of a model alone rarely dictate its values but if you favor reputability, it’s widely advised that you remember the following manufacturers

  1. We purchased a VINGLI waste tank to empty our travel trailer’s grey tank when we are not near “hookups”. The quality of the construction is excellent, with giant wheels for easy movement, and the price is less than half of the other brands we looked at. This makes transport and filling easy.
