Shipping at roughly 103 pounds, the Ronco RVB310 carries the thickest wall in its 45 gallon class of RV fresh water tanks. That extra polyethylene translates directly into stiffness and long-haul durability for a tank that will spend decades strapped under a coach. It is a light-duty potable water tank, the standard rating for RV drinking water systems.
Ronco molds the RVB310 from natural polyethylene that is FDA compliant for fresh water contact. The material is left uncolored, so the translucent wall shows the water level from outside, and the whole vessel is formed in one piece by rotational molding, seamless from top to bottom. It is produced at Ronco Plastics' Tustin, California facility, running since 1974.
As with every tank Ronco builds, the RVB310 is completed to order: spin-weld or threaded fittings are installed at the locations your specification requires, so fill, vent, and outlet arrive where your plumbing expects them. Where a drawing appears it shows the blank molding. OneSource Plastics supplies the RVB310 as an authorized Ronco Plastics dealer.
