Reviews of the 5 Best RV Portable Waste Tanks

Okay, let’s get into each of our recommendations and their pros and cons.

Best 4-Wheel Portable Tank

Barker 4-Wheel Tote-Along

The Barker 4-Wheel Tote-Along is an excellent portable waste tank that makes transporting waste friendly and straightforward. Not only is this our top pick for 4-wheeled tanks, but it’s top-rated choice for other full-time RVers.

Sturdy blow-molded polyethylene, zinc-plated steel, and aluminum make up this tank. These materials are ideal for outdoor products because they prevent sunlight from wearing down the tank.

This tank is mounted to a plate on durable wheels, making for smooth and quiet maneuvering of waste back and forth. A huge bonus with this product is that it comes with a three-inch waste valve, eliminating the need to lift the tank to empty the waste.

This product is available in a 42-gallon tank and comes with the following additional items:

  • Two, three-inch bayonet caps
  • One, three-quarter-inch cap
  • One three-by-five sewer hose
  • Two, three-inch bayonet hose adapters
  • Two hose clamps
  • One tow handle
  • Filler hose assembly kit
  • Full tank indicator

Best Portable Tank for Small RVs

Barker 2-Wheel Tote-Along

The Barker 2-Wheel Tote-Along is a quality portable tank perfect for small RVs. This tank also has an average customer satisfaction rating of 4.6/5 stars. Top-notch blow-molded polyethylene construction and zinc plated brackets make up this 30-gallon tank. It also comes with the following additional items:

  • Tow bracket
  • Sewer hose
  • Three-quarter-inch garden cap hose
  • Three-inch bayonet cap
  • Two, three-inch hose adapters
  • Two adjustable clamps
  • Drain hose
  • Two wheels
  • One handle

The Barker 2-Wheel Tote-Along is another superb candidate when it comes to transporting waste. With its handle and wheel system, you can easily pull this tank to a waste station. Emptying this tank involves minimal lifting. All you have to do is unscrew the cap, connect the hose to the tank, tip the tank ninety degrees, then pour in the dump station.

Even though it’s a portable tank, I recommend having two people handle this portable tank. If one person supports the hose and another person dumps the tank, the waste disposal process is much easier.

Most Affordable Portable Tank

Maintaining your RV is important, but can often be expensive. If you’re looking for a durable portable tank that’s also budget-friendly, I strongly recommend the 4-Wheel Tote-N-Store. It offers the best of both worlds in terms of reasonable price and quality.

This portable tank comes fully assembled with an eighteen-gallon tank, three quarter inch cap, three-inch hose adapter, fifteen-inch garden hose, a waste drain hose, clamps, four wheels, and a handle.

The 4-Wheel Tote-N-Store also makes transporting waste simple with its easy to maneuver handle and wheel system. The tank’s construction is instrumental in not requiring lifting to empty and that it doesn’t expand upon filling.

Recap: The Best Portable Waste Tanks For Your RV

Factors To Consider When Buying a Portable Waste Tank

Emptying out your black water tank and grey water tank is messy business. You need a portable waste tank that you can rely on!

While all portable RV waste tasks serve the same purpose, there are several factors to consider before selecting the right one for your needs.


The size of the tank you choose is undoubtedly important. If you have a large RV, do you have to select a large tank? Not necessarily. When choosing the size, think about your needs. Are you traveling for a long time or just a few days? Will the size of the tank affect how easily you can move and empty the tank?

Smaller tanks might mean emptying more often, but they are often easier to move around.

For example, the 4-Wheel Tote-N-Store sits higher than the other tanks mentioned and doesn’t always fit older RVs. It’s crucial to measure the height of your RV and compare it with tank dimensions to ensure adequate clearance before making a purchase.


Like the size, it’s essential to consider the weight. Depending on the product weight itself and the volume of waste the portable tank carries, it may be too heavy and require an extra set of hands to empty. If you’re using your RV solo, you may want to consider a tank that doesn’t require lifting to dispose of waste.


The portable tank structure is another crucial factor to consider, specifically the integrity of the wheels. As a rule of thumb, you shouldn’t transport these portable tanks at speeds above five miles per hour. If you were to tow one of these tanks faster than five miles per hour, you run the risk of damaging the product and, as a result, will not receive warranty coverage.

It’s also important to keep in mind that not every product is created equal in transporting across uneven or soft terrains, such as gravel or grass. Whenever possible, it’s the least amount of hassle to maneuver your portable tank on pavement or another smooth surface. If you do have to handle a tank across uneven or soft landscapes, exercise caution.


Another critical factor to consider is the manufacturer’s warranty. These portable tanks vary with warranty packages and what each warranty covers. It’s always best to check with the manufacturer for specific warranty details and coverage for each product. If your product warranty expires and parts break, you can easily order replacement parts through the manufacturer.

As you can see, there are several legitimate options for purchasing RV portable waste tanks. However, there is no “one size fits all” choice for buying a portable waste tank.

Before purchasing, determine what size tank you need, what features matter most to you, warranty and part replacement options, tank structure, and integrity, maneuverability on various terrain textures, and measure your RV height to ensure the tank will fit.

Frequently Asked Questions

How Do You Transport A Portable Waste Tank?

The best way to transport a portable waste tank when you’re on the move is to put it under your RV and strap it down to the floor with either rope or ratchet straps to keep it from sliding or tipping over. It is best to also transport your waste tank in your RV when it is empty as the contents can spill while you’re driving.

How Long Do Portable Waste Tanks Last?

Depending on the size of your RV, as well as how many people you are with, waste tanks can last up to 5 or 6 days. It is best to empty and clean your tank regularly because the last thing that you want to happen is for your waste tank to be completely full.

Can You Put Bleach In An RV Waste Tank?

One of the easiest ways to clean a tank is with bleach. While it is not recommended to let the beach sit in the tank for a long period of time, it will eat away anything that is in the tank and help keep it clean. It is also not recommended to put straight bleach in your tank, diluted bleach will accomplish the job in almost the same fashion.
