Best Portable Waste Tank for RV Owners

An RV portable waste tank is a container that keeps waste from your grey or black tanks while you move it to a disposal site. The portable tanks expand the capacity of the RV’s waste tanks, which is essential while staying at a campground without a sewer connection. You can travel on an extended vacation even if there isn’t a local trash dump facility.

An RV portable waste tank allows you to empty the contents of your gray and black waste holding tanks without breaking camp to get to a disposal site. The portable waste tanks for RVs have wheels. Some models feature two wheels in the back of the tank, while others have four wheels on each side.

When you move a two-wheeled portable waste tank, it “stands up” on end, and you must raise and hold the front section. You must maintain a two-wheeled trash tank upright while emptying its contents at the dumpsite. It is possible to roll a four-wheeled portable RV waste tank without needing to support it. When you need to discharge the trash, you can leave a four-wheeled portable RV waste tank level with the ground. It doesn’t need to be supported because it’s OK in its current horizontal posture. 

Remember that a full waste tank is quite weighty. Dumping the waste using a two-wheeled trash tank becomes more difficult as a result. However, the primary benefit of this model is that it is less expensive than the four-wheeled portable RV waste tank.

We’ve put together a buying guide to assist you in selecting the best portable waste tank for your camper.


You must select the appropriate RV portable waste tank. There are tanks designed particularly for the gray or black waste tank and tanks that can hold both types of waste.

To grasp the difference between a gray and black water tank, first learn what they are. The gray tanks will handle waste from the kitchen, sink and shower in the gray water tank. The black tanks hold waste from the toilet.


Portable RV trash tanks come in various capacities, ranging from five to more than forty gallons. You must first determine the size of your camper’s black and gray tanks to select the appropriate portable waste tank. It is not advisable to get a portable waste tank that is smaller than the waste holding tanks in your RV.


Not every portable RV waste tank is the same. These tanks come in various materials, including plastic, polyethylene, and polypropylene, with some metal components thrown in for good measure. The construction method used and the materials utilized will determine how long they last. Achieving a balance between weight and durability is critical. Experts propose investing in a polypropylene or polyethylene portable waste tank.

Because polyethylene waste tanks are long-lasting, they are a popular choice among RVers. However, it is more expensive, and some users have complained that they smell when the tank is full. The weight of a tank constructed of polypropylene is lower. It’s also less expensive than ones manufactured of polyethylene. It also performs a better job of preventing the tank’s unpleasant odor from escaping.

You must inspect the product’s quality and construction. With higher quality comes the guarantee that there will be no leaks and that you will have years of lasting service. Take a look at the portable tank’s wheels. They should be strong enough to withstand the weight of the cargo as they travel from your RV to the dump station. Under this level of strain, cheap plastic wheels would snap. The axle and other components that keep the wheels in place should also be considered. They should be built of heavy-duty materials to prevent the portable tank from being twisted or broken during transit to the waste dump station.

However, because the old saying goes, you get what you pay for. A more significant price tag is usually linked with superb quality. Regardless, you can count on a hassle-free experience when you use it. You won’t have to deal with the hassles of leaking or cracked wheels.



A flush valve is not always included in all RV portable waste tank models. On the other hand, the flush valve tanks are much easier to operate since all you have to do is enter the drain line through the valve, and gravity will do the rest.

Draining waste tanks without a flush valve is more challenging. The content will have to be manually removed. It’s not difficult to see why so many people dislike it. Consider how unappealing, odorous, and dirty it may become!

Examine the features and customer evaluations of the portable RV waste tank you want to purchase. It’s preferable if they include a function that decreases the danger of clogging since this will make dumping time simpler.


It is essential that you properly maintain your portable waste tank for your RV tanks to remain functional for an extended period.

Examine critical characteristics that will make cleaning the RV portable waste tank easier. Consider the accessories you’ll want for its upkeep so you can put the necessary measures in place to ensure that it continues to function correctly.
