The RVB388 rounds out Ronco's 15 gallon light-duty fresh water group with a polyethylene RV tank shipping at 19 pounds. It fits the same mission as its siblings, potable storage for trailers, campers, and van conversions, in a molding whose shape may be the one your bay actually accepts.
Because plumbing never lands in the same place twice, Ronco treats port location as part of the order: spin-weld or threaded fittings are installed to your specification before the tank ships, standard on every Ronco tank. Drawings shown with the listing depict the blank molding before that work.
Materially, the RVB388 is FDA-compliant natural polyethylene, correct for drinking water, with the translucent wall that lets Ronco fresh tanks show their level through the wall itself. It is rotationally molded by Ronco Plastics in Tustin, California, a company making polyethylene tanks since 1974. OneSource Plastics is an authorized Ronco Plastics dealer.
