The Barker 30844 tops our list for the largest capacity at 42 gallons, which is four more gallons than the next closest competitor. On top of that, this portable waste tank works just as well, whether you need it to hold black or gray water.

The Barker 30844 is also easy to use for both filling and emptying, the former thanks to a full-tank indicator to prevent overfilling. Emptying this tank is made easier first because the design allows for a natural flow and second because of a closing valve to prevent accidental messes.

The body is made of blow-molded PP and reinforced with zinc-plated steel and aluminum to prevent damage.

Bottom Line: With an enormous capacity, a great filling and emptying design, and an extended handle suitable for towing, the Barker 30844 is an obvious choice.

Why You Should Consider Buying an RV Waste Tote

Even if you do not camp in a secluded location, an RV waste tank might still come in handy. Unless you remain especially vigilant concerning your RV’s waste capacity, you may need to empty its waste on the fly.

Having an RV waste tank allows you to empty your RV’s waste without having to stop at a specific location. Conversely, an RV waste tank can provide a little bit of extra capacity, acting as a backup tank until you can reach a proper disposal area.

Things to Consider When Buying an RV Portable Waste Tank

Type of Tank

The type of RV waste tank refers to the kind of water that the tank can hold, with the two main types being gray and black holding tank. Gray water waste tanks hold RV water used for other purposes like taking a shower or other washing tasks.

RV waste tanks designed to be a portable black water tank can handle sewage exclusively without suffering any durability concerns. Keep in mind, manufacturers often design RV waste tanks for a particular purpose, and they may not withstand the use of another purpose.

Materials Used

Because RV waste tanks hold liquids, they need to be made out of materials that resist rust or corrosion. In general, most RV waste tanks are made out of durable plastic with polypropylene (PP) and heavy-duty polyethylene (HDPE) being the two most common.

Both of these materials do not have to worry about water or other liquids ruining their structural integrity. On top of that, neither of these materials leach environmental hazards, making them non-toxic.

Between the two, PP is more durable and rigid than HDPE and also has a higher melting point. On the other hand, HDPE is lighter than PP, which is especially important when emptying a full waste tank.

It is also worth noting that HDPE is often a little bit less expensive than PP because of PP’s superior durability.

Ease of Use

This is easily one of the most important factors to consider, especially if you use a portable tank to hold and dispose of black water. While a couple of stages can be made more or less difficult, emptying the waste tank cleanly is likely a top priority.

Waste tanks with standard size ports are a must unless you are okay with purchasing an adapter or looking for a non-standard sewer hose. Some tanks even include a hand valve to help you flush the waste from the tank.

Outside of emptying the tank, cleaning the tank to prevent the development of odors or buildup of bacterial hazards is also incredibly important. Most RV portable waste tanks provide instructions for how to clean and disinfect them, but some are more effective than others with a single cleaning.

Finally, keeping track of how much waste is in the tank is also essential, with many options employing anti-overflow features. That said, plenty of portable waste tanks also include different types of capacity indicators, but this is not the most important thing to look for.

Portability

Along with ease of use, portability is just as important, especially once your tank is filled. While all portable waste tanks come with wheels, some of them come with 4-wheels while others only come with 2.

Even with the 4-wheeled models, you can find portable waste tanks that use separate casters to offer a bit more stability. Alternatively, some 4-wheeled portable waste tanks use axles, so there are fewer parts to have to worry about.

Outside of the wheels, the handles also come into play with some handles designed more for you to pull the portable waste tank. Other handles feature particular designs or are made out of metal, which makes them better suited for being towed behind your vehicle.

Of course, you do not only move a tank while it is full, so its overall weight helps determine how easy it is to store when not in use. Also, consider whether or not the tank has handles or hooks designed to make picking it up while empty easier.

Length of Your Trip (Size)

Portable waste tank capacities are rated in gallons, though you may not necessarily need the largest model available. If you go on a longer trip and do not expect to camp in or near RV parks, you will likely want to use a tank with a larger volume.

On the other hand, if you tend to stay in RV parks or near camping grounds, a smaller portable waste tank is usually sufficient to get by until you reach a dumping area. That said, unless you have unusually low capacity needs, you should probably look for a tank with at least 20 gallons but preferably 25 gallons or more.
