Ronco Plastics RV68W - 53 Gallon Light Duty RV Fresh Water Tank

Fifty-three gallons is an in-between size, and in-between sizes are usually replacements: the RV68W most often goes to owners matching a failed OEM tank whose bay will not take the common 55s. Ronco Plastics molds it as a 71 lb light-duty fresh shell whose exact footprint is on the drawing below - print the drawing below first, compare it to the old tank, and mark your fitting locations while you are at it.

The spec beats most OEM originals: FDA-compliant natural polyethylene, translucent so the level reads through the wall, rotomolded in one piece without seams. Full, 53 gallons weighs about 442 lb - nearly the same structural ask as the 55s, so existing mounts usually carry it without drama.

Bracketing it: the 52-gallon RV8W at 60.25 x 20.12 x 11 inches goes longer and shallower, and the 55-gallon RV48W at 40 x 24 x 14 inches adds two gallons in a compact box. Fittings are installed to order - spin-weld or threaded - at the Tustin, California plant where Ronco has built tanks since 1974. The full ladder is under RV water tanks in the Ronco Plastics line.
