Topping out this stretch of Ronco's light-duty fresh water range, the RVB480 holds 19 gallons of potable water and ships at 26 pounds. That capacity suits travel trailers, fifth-wheels, and expedition-style van builds planning genuinely long intervals between water fills.
The RVB480 is rotationally molded by Ronco Plastics in Tustin, California, a company that has specialized in polyethylene tanks since 1974. Drinking water service calls for FDA-compliant natural polyethylene, and the translucent wall gives you a permanent visual on the water level with no sensors involved.
The final configuration is set by your order: Ronco installs spin-weld or threaded fittings at the locations you specify, standard treatment for every tank it molds, so the RVB480 arrives matched to your plumbing plan. A drawing, when shown, depicts the blank molding before fitting installation. OneSource Plastics is an authorized Ronco Plastics dealer.
