Replacing or specifying a 48 gallon fresh water tank for an RV usually comes down to shape, and the Ronco RVB306 exists to cover a molded profile its same-capacity siblings do not. It is a light-duty potable water tank shipping at about 95 pounds, wall thickness that puts it firmly in the heavy-service end of the class.
Ronco molds the RVB306 from natural FDA-compliant polyethylene. No colorant goes into the resin, which keeps the water-contact surface clean and leaves the wall translucent enough to read the water level by eye. The rotational molding process, Ronco's specialty in Tustin, California since 1974, yields a one-piece seamless shell with no welds or joints anywhere in the vessel.
Ordering is where the tank becomes yours: Ronco installs spin-weld or threaded fittings at the exact locations your specification defines, standard on every tank it builds, so fill, vent, and outlet match your coach rather than a generic template. Drawings, where shown, depict the blank molding. OneSource Plastics supplies the RVB306 as an authorized Ronco Plastics dealer.
