The RVB564 comes off Ronco's B-564 tool as the light-duty variant: 24 gallons of fresh water capacity in translucent natural polyethylene, molded for RV service where the tank rides cradled in framing rather than fighting a seaway. Light duty is a wall-thickness class, not a quality grade - it is the correct spec when the coach structure, not the tank shell, carries the working loads.
The translucent wall is the practical touch: water level reads through the tank at a glance, no gauge, no guesswork. It is FDA-compliant potable material throughout, and at a 26 lb blank weight it is genuinely a one-person install. Full, plan for about 200 lb of water and mount over frame members, not floor skin.
Fittings are installed per order at the Tustin, California plant - spin-welded or threaded to the marks you supply, as Ronco has done since 1974. Print the drawing below, place fill, vent, and outlet against your plumbing runs, and lock them in with the on-page fitting planner.
Close neighbors in capacity include the 25-gallon RV49W; the complete size run is under RV water tanks and the whole catalog on the Ronco Plastics hub. OneSource Plastics is an authorized Ronco Plastics dealer.
