For a 28 gallon fresh tank that stays light, Ronco's RVB273 ships at 26 pounds, under a pound per gallon of capacity. It is a light-duty RV fresh water tank rotationally molded by Ronco Plastics in Tustin, California, where polyethylene molding has been the business since 1974.
The tank is FDA-compliant natural polyethylene, matched to potable water, and its translucent natural wall makes the water line visible through the tank itself during fills and throughout a trip.
As on all Ronco tanks, fittings are installed per order: spin-weld or threaded, positioned to the customer's specification so the tank meets your plumbing rather than the other way around. Drawings shown depict the blank molding. OneSource Plastics is an authorized Ronco Plastics dealer.
