“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 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 attache to the axle.
