The Camco Rhino is the heaviest duty option for portable RV waste holding tanks. It is available in four sizes: 15 gallons, 21 gallons, 28 gallons, and 36 gallons. All sizes come with wheels for easy transport.

Thanks to its blow-molded UV-stabilized high-density polyethylene (HDPE), it will not degrade in the sun and will not leak over time.

It has a ladder hook on the top to be easily hung on the ladder of an RV or trailer when empty. It also has molded-in grooves for straps to ensure a secure fit.

Note that the RV portable dump tank should not be towed faster than the walking speed. Pulling too fast can damage the wheels and tank. The 36-gallon Camco Rhino Tote Tank is also available in a 4-wheel version. 

It has two wheels made of durable rubber on the back to be towed like a suitcase. It also comes with a towing bracket that allows you to lengthen the handle when pulling the tank or connect it to a ball hitch to tow it with your RV.

Two things make the Camco RV waste tank one of the best: the sewer outlet option and the rinse valve. At the bottom of the tank, by the wheels, there is a standard sewer connection. This connection can be used to fill the tank, or you can stand the tank up and empty it.

The best feature of this waste tank is the connection for the spray rinse; the RV waste tank has a vent for air, but Camco has provided a female hose connection for water. When water is added, the spray inside the tank will flush out the tank.

The following accessories are included with this product:

It’s similar to the black tank flush system found on high-end RVs and trailers. The unique feature that only the Camco Rhino has, and it puts its head and shoulders above other RV waste tanks.

The only downside is that it becomes very tall when lying down, which can be a problem if the sewer outlet is very close to the ground. Some people do not like the idea of having a portable waste tank up high, although waste from black or gray tanks should be able to be dumped into the tank even if it is a little taller due to the force of gravity.
