At 260 gallons, the Ronco Plastics B284 is less an RV accessory than a bulk water system: a broad, low slab of a tank - 61.25" x 59" x 18" - built to lie flat in a basement bay, a truck bed, or the belly of a large coach or toy hauler. The proportions are the whole story. Keeping 260 gallons only 18" tall keeps the center of gravity down where a rolling vehicle wants it, and the wide footprint spreads the load across the frame instead of pointing it at one crossmember.
Spread or not, the load is serious: about 2,168 lb of water when full, on a molding that itself weighs 190 lb. Support the tank across its entire bottom - full-sheet, not rails - and strap it against surge. Ronco installs every fitting per order, spin-weld or threaded at your marked locations, which on a tank this wide lets you put the outlet exactly over your pump and the fill exactly under your hatch. Print the drawing below and work the positions out with the on-page fitting planner; the FDA-grade polyethylene keeps the whole supply potable.
Molded in Tustin, California by a company that has done nothing but this since 1974, the B284 anchors the big end of our RV water tanks. A tank this size ships by freight, so run your ZIP through the freight cost estimator before you commit. OneSource Plastics is an authorized Ronco Plastics dealer.
