The RVB355 is a 21 gallon light-duty RV fresh water tank from Ronco Plastics, notable for its stout 81 pound shipping weight. Rotationally molded in Tustin, California, at a plant running since 1974, it serves the potable water side of trailers, campers, and conversions in the 21 gallon range.
Its FDA-compliant natural polyethylene construction is safe for fresh water, and the translucent natural resin lets you check the water level straight through the tank wall. One-piece rotomolding leaves no seams to fail.
You specify the plumbing points when you order: Ronco supplies and installs spin-weld or threaded fittings located to your specification, the standard treatment on every tank it molds. If the listing includes a drawing, it depicts the blank molding. OneSource Plastics is an authorized Ronco Plastics dealer.
