The Ronco Plastics B482 sits at 49 gallons, a capacity that covers a genuine cruising week of fresh water or a long interval between pump-outs, depending on which tank you tell Ronco to build from this dual-role shell.
The mechanism is simple and it never varies across the B-series: the molding is a blank, and the fittings you order define the tank. Fresh water fittings produce a potable tank, its polyethylene food-grade; waste fittings produce a gray or black holding tank. Every fitting is installed per order at the factory, spin-welded or threaded at the locations you mark, which is why the first step of ordering is printing the dimensioned drawing below and drawing on it.
Structure comes next: 49 gallons of water weighs about 409 lb at 8.34 lb per gallon, riding on a 97 lb tank. Chock it, strap it, and keep the load path into something solid. The on-page fitting planner turns your marked-up drawing into a build spec Ronco's plant can execute.
Molded in Tustin, California by Ronco Plastics, in the trade since 1974. Neighboring sizes live in the marine tank collection and the full Ronco range; delivery pricing is a ZIP code away in the freight cost estimator. OneSource Plastics is an authorized Ronco Plastics dealer.
