The RVB231 is a 20 gallon plastic RV water tank from Ronco Plastics, rotationally molded in Tustin, California, where Ronco has built polyethylene tanks since 1974. It ships at 22 pounds and provides fresh water storage for trailers, campers, and van builds in the 20 gallon class.
Molded in FDA-compliant natural polyethylene as a single seamless piece, the tank's translucent wall shows the liquid level directly, sparing you a separate sight tube for everyday fills and monitoring.
Ronco's fitment policy applies: spin-weld or threaded fittings are installed per order at locations you specify, which is how every Ronco tank ships. A drawing, if shown, depicts the blank molding before fittings are added. OneSource Plastics is an authorized Ronco Plastics dealer.
