7 Best RV Portable Waste Tanks of 2021

by Joshua Thomas

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.

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.

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

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.

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.

  • Rugged build construction. Very durable and long-lasting
  • Hidden compartment for storing all your accessories

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 similarly 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

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