In some cases having a portable RV waste tank can be a lifesaver. An RV waste tote tank lets you dump the black water tank anywhere you are so you can continue on your trip. They are available in a variety of sizes and can double your black water capacity. If you are boondocking the extra black tank capacity is extremely useful. If you happen to be parked where there is no dump station or it’s too far then using the RV waste tote might be your only option. It is easier to transport the filled waste tank to the dump station than it is to pack up your camper and drive it a few hundred feet to the dump station.

  • You get everything you need to transport waste from your RV to the dump station
  • It includes all the accessories you need to clean, maintain and store the tote
  • Wheels are no-flat with bearing to provide a smooth transport

In addition to the above features, it has a removable tow adapter. This adapter allows you to roll the tote tank just like you would roll luggage.

The drain hole on this portable RV waste tank was placed low to ensure it drains completely.

The Camco Rhino has a smooth interior so it’s easy to clean with the integrated tank rinser. You can easily hang it from your RV ladder with the integrated ladder hook.

The Camco Rhino portable RV waste tank comes with a generous two-year warranty. It comes with everything you need:

  • Bayonet and lug storage caps for the hose
  • Steel tow adapter
  • Caps with lanyards

Here is just a sampling of what owners have to say:

“I purchased the 28-gallon portable Rhino Tank to save me from having to hook up the 5th wheel and dump the tanks. This tank works wonderfully.”

I bought the 36 gallon not really thinking through how gigantic it would be. This thing is huge. It appears well built. I like the accessories that came with it.

There are some things you need to keep in mind if you purchase the Camco Rhino. Some buyers have had problems with the wheels coming off.

The wheels use a snap cover to keep them attached to the axle. Several users have removed the snap caps and drilled a hole through the axel and added cotter pins and SS washers.

Overall we highly recommend the Camco Rhino. It is one of the best-rated portable RV waste tanks on the market today.

Easy to use, has all the accessories you need and is made of very durable materials with a two-year warranty as well. You can go wrong.
