The RVB257 rounds out Ronco's 20 gallon light-duty fresh water offerings for RV use, shipping at 22 pounds. Like every tank in the line, it is rotationally molded at Ronco Plastics in Tustin, California, where polyethylene tanks have been produced since 1974, and it is meant for the potable side of an RV plumbing system.
Its FDA-compliant natural polyethylene wall is translucent, turning the tank into its own water gauge, and the one-piece rotomolded construction has no seams to leak as the coach works over rough road.
Choose your fitting map when you order: Ronco supplies spin-weld or threaded fittings installed to the customer's specification, standard on all its tanks, with any published drawing depicting the blank molding. OneSource Plastics is an authorized Ronco Plastics dealer.
