At about 10 pounds shipping weight, the Ronco RVB326 is the lightest of Ronco's 7 gallon fresh water moldings, a light-duty potable tank for the small end of RV service. Weight-critical builds, motorcycle campers, teardrops, and rooftop-tent trailers all benefit from a water tank that barely registers on the scale empty.
Its 7 gallon supply rides in a one-piece rotationally molded shell of natural FDA-compliant polyethylene. No pigment goes into the resin, which keeps the water-contact surface clean and leaves the wall translucent enough to read the level from outside. And because the molding is seamless, there is no joint anywhere in the tank to fail.
Ronco Plastics builds the RVB326 in Tustin, California, rotomolding tanks there since 1974, and its standard order process applies: spin-weld or threaded fittings installed at the locations your specification calls out, so the tank arrives ready to plumb. Drawings, where shown, depict the blank molding. OneSource Plastics is an authorized Ronco Plastics dealer for the RVB326.
