RVB556 is a 20 gallon light-duty RV fresh water tank molded in FDA-compliant natural polyethylene, whose translucent wall doubles as a sight gauge so you can check remaining water without instruments. Sized for travel trailers, camper conversions, and truck campers, it ships at 25 pounds.
Ronco Plastics rotationally molds this tank in Tustin, California, drawing on rotomolding experience that goes back to 1974. The result is a seamless one-piece vessel, the construction that has made poly the default material for onboard fresh water.
Ronco finishes each RVB556 to order, installing spin-weld or threaded fittings at the positions your plumbing plan specifies, its standard practice on every tank. If a drawing is shown, it depicts the blank molding before fittings. OneSource Plastics is an authorized Ronco Plastics dealer.
