The Ronco Plastics B299 puts 80 gallons of fresh water into a long, shallow RV molding made to slide under a floor or bed platform rather than stand in a bay. Keeping the profile low keeps the coach's center of gravity where the chassis engineers wanted it - a genuine handling difference once you are carrying about 667 lb of water on a molding that itself weighs 126 lb.
Ronco ships the tank as a sealed blank and installs spin-weld or threaded fittings per order at your marked spots. Long shallow tanks live or die on port placement: the outlet must land at the low point of the tank as installed, not as drawn, and the vent has to reach the high end or the last gallons will glug instead of flow. Print the drawing below, mark it against your actual floor slope, and settle the layout with the on-page fitting planner. FDA-grade polyethylene keeps the entire supply potable.
Built in Tustin, California, where Ronco Plastics has molded RV and marine tanks since 1974, the B299 slots into the big-capacity end of our RV water tanks. Pair it against a matching waste tank from RV holding tanks and check delivery with the freight cost estimator. OneSource Plastics is an authorized Ronco Plastics dealer.
