Eighty gallons of fresh water is boondocking range - a week off-grid for a careful couple - and the RVB230 delivers it as a single molding rather than a plumbing project joining two smaller tanks. On Ronco's own light-duty sheet it is the B-230 L.D.: wall thickness matched to a supported RV installation, so the capacity comes without the weight penalty of marine-grade wall.
The tank is translucent natural polyethylene with FDA approval for potable water. Translucence matters more as tanks get bigger: at this capacity a failed level sender means real uncertainty, and being able to see the waterline through the wall is the gauge that never breaks. Ronco installs your fittings per order - spin-welded or threaded, at your marked locations - so plan the ports before it is molded. Print the drawing below and work the layout through the on-page fitting planner.
Ship weight is 120 lb, and a tank this size should be specified with the bay, not squeezed into one: confirm the compartment and the floor structure first, because the loaded tank is by far the heaviest single item in most coaches. Molded in Tustin, California, where Ronco has run since 1974.
The large light-duty moldings cluster at the top of our RV water tank category - the RV70W sits just above this size if the bay allows. Everything else is on the Ronco Plastics hub, with delivery quoted by ZIP in the freight estimator. OneSource Plastics is an authorized Ronco Plastics dealer.
