The Ronco RVB319 is an 11 gallon light-duty polyethylene RV water tank with a 22 pound ship weight, the heaviest molding among Ronco's 11 gallon fresh tanks, which suggests a shape and wall build suited to bays where the tank is well supported and longevity is the priority.
Potable duty calls for the right material, and the RVB319 is molded from FDA-compliant natural polyethylene. Its translucent wall shows the water line through the tank, a simple level check that never fails. Production happens at Ronco Plastics' rotational molding plant in Tustin, California, in operation since 1974.
As with every Ronco tank, port placement is customer-driven: spin-weld or threaded fittings are installed at the locations you specify when ordering, and a drawing, when present, shows the blank molding before that step. OneSource Plastics is an authorized Ronco Plastics dealer for the RVB319 and the rest of the line.
