Ronco Plastics RV66W - 95 Gallon Light Duty RV Fresh Water Tank (67.0" x 22.0" x 16.0")

The RV66W is what a big fresh water tank looks like when it is designed for a coach instead of a warehouse: 67 inches long, 22 wide, only 16 tall. Ninety-five gallons, the largest capacity in Ronco's light-duty W-series, laid out as a long low slab that runs between frame rails or across a basement bay without eating vertical space. Sixteen inches of height is the difference between a tank that fits under the floor and a tank that needs a compartment redesigned around it.

Ninety-five gallons is serious autonomy, and serious weight: about 792 pounds full, which is why the long footprint matters as much as the capacity. Spread across 67 x 22 inches and mounted low, that mass sits where a chassis carries load best. The molding ships at 85 pounds, seamless rotomolded FDA-compliant natural polyethylene from Ronco's Tustin, California plant, translucent enough to check level through the wall. Since 1974 Ronco has shipped these as blank moldings and installed spin-weld or threaded fittings per order, and on a tank this long that is not a nicety, it is the install: your fill, vent, and pump pickup locations depend entirely on which end sits high after mounting.

Print the dimensional drawing from the link below, mark the fitting locations off your actual bay measurements, and order to the marks. If the bay is shorter than 67 inches, the W-series has a dozen intermediate sizes, from the 14 gallon RV3W up through the 43 gallon RV12W, all in RV water tanks; the whole maker-documented line is under Ronco Plastics. A tank this size ships LTL, quoted live to your ZIP by the freight estimator. OneSource Plastics is an authorized Ronco Plastics dealer.
