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.

1. Tote-N-Stor 25608 – Lightweight and Easy to Carry

Tote-N-Stor 25608 RV Portable Waste Tank

Photo: Tote-N-Stor

  • 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 has a run 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 family of 3 or more, this model will quickly show its limitations as it is too small with its capacity of 25 gallons.

All in all, if you are looking for a modestly priced RV portable holding tank then 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. 

Pros:

  • Lightweight at 22 lbs. Easy to carry around
  • A rugged build construction. Durable and long-lasting
  • Uses a 3 inches drain hose for easy drainage
  • Easy to move around thanks to its 2 rubber wheels

Cons:

  • The capacity could have been a little bit higher for the price
  • Comes with only 1 fitting for the waste tank

2. Barker 31342 – Slim and Compact 

Barker 31342 RV Portable Waste Tank

  • 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. In addition, 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 when compared to other models on the market.

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. 

Pros:

  • Slim and compact. Easy to carry and install
  • Built from a molded polyethylene material. Very durable and long-lasting
  • 5 inches sewer hose allows you to drain it very quickly
  • Out of the box, this model comes completely pre-assembled

Cons:

  • The biggest model only has a capacity of 30 gallons
  • Basic design and features

3. 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 gallon 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 makes 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.

All in all, if you’re looking for a quality model then this unit from Camco is rated by many as being 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 which makes it hard to known when the tank ifs full.

Pros:

  • Can be purchased in different capacities to suit your need
  • Quality build construction. Deep attention to detail
  • The wheels are equipped with ball bearings. Very smooth and easy to move around
  • Due to the internal and external designed of this waste tank, it will not leak and is free from odors

Cons:

  • No level indicators

Photo: Tote-N-Stor

  • 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 for you 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.

Pros:

  • The large capacity of 32 gallons. Able to hold more waste
  • Rugged build construction. Very durable and long-lasting
  • Hidden compartment for storing all your accessories
  • Lightweight at 26.8 lbs. Easy to move around

Cons:

  • The hose delivered with this purchase is shorter when compared to other models

  • 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.

In addition, 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 definitely its level gauge that will show if this portable waste tank is getting full or not. This is a feature that is sadly missing from other models but which is highly useful.

All in all, if you are looking for an easy to use a waste tank that is easy to carry around and is quite lightweight as well, 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.

  • Pre-assembled and easy to install by beginners
  • Equipped with 4 wheels. Very easy to move around
  • Due to the modern design, it is odorless and will not leak easily
  • Level gauge indicator that shows the capacity status

Cons:

  • 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 in such a way 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 tank you can get.

Pros:

  • The large capacity of 42 gallons
  • Ability to choose different capacities and sizes
  • Very easy-to-use by even absolute beginners

Cons:

  • The price could have been more attractive

  • 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 tank on the market.

Pros:

  • Premium build construction. Extremely durable and long-lasting
  • Easy to move around due to the rear rubber wheels and front casters
  • Auto stop feature to prevent spills
  • Contains a dedicated compartment for storing the hose

The duration of your trip will dictate the size and capacity of the RV portable waste tank. In general, the longer you are planning to stay in your RV, then the bigger the portable wasteland needs to be.

One of the good things about the RV portable waste tank is that it comes in different sizes. There are models that are small and can accommodate only 10 gallons of waste.

However, if you need a bigger waste tank, no problem. You can safely go with a 42 gallons tank which will be more than enough, especially if you plan to camp with a small family for a few days.

2. Capacity

The size or the capacity of the portable waste tank is directly linked to the duration of your trip we have just discussed above.

In short, if you are planning to stay for a longer period of time and have many people with you, then to be on the safe side it is always recommended to go with a larger capacity RV portable waste tank.

In general, anything above 25 gallons will be more than enough but if you think that this will not be enough then you probably want to invest in a portable waste tank of 42 gallons.

Note that the bigger size of your RV portable waste tank, the more time it will need to dump and clean.

3. 2-wheel or 4-wheel RV Portable Waste Tank

Most top-rated RV portable waste tanks on the market come in either 2 wheels or 4 wheels form factor.

A 2-wheel RV portable waste tank is generally intended to be kept vertically and tilted to an angle during transportation.

On the other hand, the 4-wheel RV portable waste tank is much easier to move as it behaves similar to a cart and all you have to do is pull on the handle to move it around.

When choosing between those 2 types of portable waste tanks, remember that price matters. A 2-wheel RV portable waste tank is generally cheaper than a 4-wheel model.

4. Easy to transport

Most of the time, you will need to carry the RV portable waste tank to the dumping ground. When this waste tank is full, it can be very heavy, especially if you go with a 42 gallons model.

Therefore, it needs to be equipped with wheels as well as a handle that will allow you to easily transport it.

5. Durability

You do not want an RV portable waste tank to leak. In fact, this is the last thing you want to happen especially when out camping. In order to prevent this problem, go with an RV portable waste tank that has a rugged design.

6. Accessories

When it comes to the RV portable waste tank, you need all the accessories you can take. This will include hoses, ports for holding your hoses, tow handle extensions and cradle pivots.

As much as possible, go with a model that is all-inclusive and contains the hose and hose brackets such that you can get started right away without the need for purchasing extra accessories outside.

7. Price

One of the things to do first before purchasing an RV portable waste tank is to set a specific budget and then try to find a model that fit this budget.

This portable waste tank is generally not very expensive, but the price can quickly rise especially if you choose to go with a model that has a large capacity and comes with many accessories and features.

In any case, you should never sacrifice quality even if it means you need to pay a little bit extra. Additionally, always go with a model that have all the necessary features and choose a size that is appropriate for your need and purpose.

Conclusion 

The fact is, if you own an RV then you absolutely must buy an RV portable waste tank as well, especially if you plan to go camping in the open for a few days.

Your inbuilt RV waste tank is usually smaller and will most likely be full quickly.  If you do not have a dedicated dumping area, then an RV portable waste tank will come in handy.

Best of all, almost all waste tanks come with rubber wheels so you can easily move it and they also have industry standard sewer valves of standard sizes for dumping the tank quickly and easily.

Finally, if you have read our RV portable waste tank review above and have still not found a good model yet, then we recommend that you go through it one more time.
