Eighteen gallons of fresh water is where a rig starts feeling self-sufficient, and the Ronco RVB211 supplies it in a light-duty polyethylene RV water tank with a 24 pound ship weight. Travel trailers, fifth-wheel retrofits, and ambitious van builds are the natural applications.
Since it feeds taps and kettles, the RVB211 is molded from FDA-compliant natural polyethylene. The translucent wall reveals the water level through the tank, a fail-safe gauge that costs nothing and never miscalibrates. Ronco Plastics rotationally molds it in Tustin, California, where the company has made polyethylene tanks since 1974.
Ronco's standard fitting service completes the package: spin-weld or threaded fittings installed per order at the locations you specify, so the tank arrives configured for your plumbing rather than needing field modification. The drawing, where shown, is the blank molding. OneSource Plastics carries the RVB211 as an authorized Ronco Plastics dealer.
