7 Best RV Portable Waste Tanks of 2021
All recreational vehicles have a dedicated waste tank for your shower, sink, and toilet. However, this waste tank is usually small and requires a dedicated sewer dumping location to empty. This can be a big problem, especially for those who go camping for days where no such dumping grounds exist.
This is why the RV portable waste tank was invented. As its name suggests, it is a portable waste tank where you can dump your RV tank’s waste into and then later discard into a dumping ground.
The main advantage of the RV portable waste tank is that it has wheels and a long handle allowing you to easily move it around.
Furthermore, a top-rated RV portable waste tank will have a meter gauge that will show you if the tank is full or not.
In addition, when you need to remove waste from the RV portable waste tank, it has a dedicated sewer valve that will securely connect to any sewer line thus preventing any bad odor or leakage during the dumping process.

Tote-N-Stor 25608 – Lightweight and Easy to Carry
- Capacity: 25 gallons
- Dimensions: 35.25 x 24 x 11.625 inches
- Weight: 22.3 lbs
This Tote-N-Stor RV portable waste tank has one unique selling point. It is an extremely lightweight model that weighs only 22.3 lbs. In fact, it is the lightest model in this RV portable waste tank review.
At such a low weight, anyone can easily move it around, no problem. Furthermore, the 2 rubber wheels of this tank make it even easier to move around.
In addition, it has an industry standard 3 inches drain hose that will be able to connect with any sewer line. Out of the box, you also get a 36 inches drain hose with this purchase that makes it even more value for money.
Moreover, this model runs the construction from a heavy-duty plastic, which means that it is very long-lasting and durable.
Best of all, it has a capacity of 25 gallons, which is more than enough for at least 2-person camping for a few days. However, for a 3 or more family, this model will quickly show its limitations as it is too small with its capacity of 25 gallons.
If you are looking for a modestly priced RV portable holding tank, this model from Tote-N-Stor is one of the best RV portable waste tank for the money.
A caveat we note is that this model comes with only 1 fitting for connecting to the waste tank. An additional fitting would have been more than welcome to connect to your RV as it would have made the installation easier and more sanitary.
Barker 31342 – Slim and Compact
- Capacity: 30 gallons
- Dimensions: 37 x 24 x 11.8 inches
- Weight: 17 lbs
The Barker 31342 is a slim and yet highly portable RV waste tank that comes in a wide range of sizes, ranging from 10 gallons up to 30 gallons. You will have no difficulty storing or installing this model because of its compact form factor.
Of course, if you choose to go with a larger capacity waste tank, it will be more expensive.
Moreover, you get everything, including the hose and hose brackets that will allow you to get started out of the box.
The 2 rubber wheels of the system make it easy to move around. Besides, at 30 gallons, this model is more than adequate for one or 2 people camping out for a few days.
But what we like the most about this model is its polyethylene build construction and zinc plated brackets that makes it very durable and long-lasting. You can easily leave this RV portable waste tank outside in the open and it will still last you a long time without getting damaged.
In addition, to empty this top-rated RV portable waste tank, it uses a 5 inches sewer hose that is bigger than the industry standard. Therefore, you will be able to empty this waste tank much faster than other models on the market.
The only problem with this waste tank is that it is has a basic design and its largest model comes with a maximum capacity of only 30 gallons.
Camco Rhino 39002 – Comes in Different Sizes and Capacities
- Capacity: 15 gallons, 21 gallons and 36 gallons
- Dimensions: 20.5 x 33 x 13 inches, 41 x 13 x 20.5 inches, 47 x 16 x 25.5 inches
- Weight: 34.5 lbs
The Camco Rhino 39002 is a somewhat futuristic and modern-looking RV portable waste tank. You can purchase this model in 3 versions: a 15-gallon waste tank, a 21 gallons model, and a 36 gallons tank for even more capacity.
But one thing that demarks this model from the rest of the competition is definitely its solid and quality build construction. There is a deep attention to detail in this Camco RV portable waste tank.
Moreover, the carry-handle at the top as well as the 2 heavy duty rubber wheels at the bottom make it very easy to move around. Best of all, the wheels use a bearings system that makes it incredibly smooth to move.
This model uses the traditional 3 inches sewer hose, so it will not be a problem draining it in any sewer line. In addition, you also get all accessories with this purchase, so you can readily use it out of the box.
If you’re looking for a quality model, this unit from Camco is rated by many as one of the best RV portable waste tanks for the money. This is a purchase that you will absolutely not regret.
A disadvantage to this waste tank is it does not have a level indicator, making it hard to know when the tank ifs full.
Tote-N-Stor 25609 – Excellent Size to Capacity Ratio
- Capacity: 32 gallons
- Dimensions: 24 x 11.6 x 5.8 inches
- Weight: 26.8 lbs
We have reviewed a very similar model to the Tote-N-Stor 25609 above. However, this current one has a 32 gallons capacity while the other was 25 gallons. It still remains slim and compact, which provides this model with an excellent size to capacity ratio.
But other than this, it is a carbon copy of the 25608 waste tank above. It has the same rugged construction that makes it very durable and an ideal candidate for those who need to keep their RV waste tank outside, in the sun or in the rain.
In addition, you get all the accessories with this top-rated RV portable waste tank, and it comes pre-assembled out of the box. There is even a molded compartment inside the waste tank to store your hose so that you do not create clutter.
Moreover, the 3 inches drain hole makes it very easy to drain. When done right, you will be able to drain it without creating any odors or leaks. The only problem is that the provided hose is a bit short. So, you will need to install this tank fairly close to your toilet if you plan to use the factory provided hose.

- Capacity: 27 gallons
- Dimensions: 42.4 x 15.4 x 21.7 inches
- Weight: 26 lbs
This SmartTote is a 27 gallons RV portable waste tank that guarantees to be compatible with any type of RV. Out of the box, this model is pre-assembled, so it is very beginner-friendly. You will have no problem installing or draining it, even if this is your first waste tank.
Besides, this model comes as a 4-wheeler so that you can carry it around more easily for drainage. The handle is also long and quite ergonomic, so it will not create any back fatigue while moving it.
Additionally, there is also a top handle if you wish to use this model as a 2-wheeler. But one of the best things that we like about this model is its level gauge that will show if this portable waste tank is getting full. This is a feature that is sadly missing from other models but which is highly useful.
If you are looking for an easy to use a waste tank that is easy to carry around and is quite lightweight, then this model from SmartTote is one of the best RV portable gray water tank that are currently on the market.
Just note that its capacity of 27 gallons is small and this waste tank is intended for no more than 3 people.

- Capacity: 42 gallons
- Dimensions: 45 x 24 x 14 inches
- Weight: 47 lbs
The Barker 30844 is a larger size RV portable waste tank built for a large family. Indeed, this model is 42 gallons so it will be able to hold a lot of waste, making it an ideal RV portable waste tank for campers.
However, since it is equipped with 2 heavy-duty wheels at the back and a front wheel, it is very easy to carry around, especially in a horizontal position. In addition, the front handle is long and ergonomic as well.
As for the build quality, this unit has a rugged construction made from thick and heavy-duty polyethylene plastic that is extremely durable. You will be able to store this waste tank outside as it is fully weatherproof.
Moreover, this waste tank has been designed so that you simply open the 3 inches valve at the bottom and simply place the waste tank in a horizontal position for it to drain. Very easy.
The only caveat is that it is heavier than other models at 47 lbs. However, if you don't plan to move this wank around often, it still remains one of the best RV portable sewer waste tanks you can get.
Thetford 40510 – Most Portable Waste Tank
- Capacity: 18 gallons
- Dimensions: 36.7 x 28 x 14.6 inches
- Weight: 10.4 lbs
The Thetford 40510 is built like a premium suitcase. However, don’t underestimate it as this is a very capable waste tank that is rated by many as one of the best RV portable black water tanks on the market. Mostly because this model is very portable as it weighs only 10.4 lbs making it extremely easy to carry around.
This is mostly due to its excellent build construction that makes it very resistant to durable and long-lasting elements. Additionally, there are 2 large rubber wheels at the back as well as front casters, which makes it very easy to move.
In order to prevent spills, this model is equipped with an auto stop as well as has a compartment for storing the hose. Out of the box, you get everything that will allow you to get started right away.
The only caveat we have is that it is a little low capacity at 18 gallons. This is still more than enough, especially if you plan a solo-experience in the outdoors for a few days.
