Ronco Plastics RV1W - 35 Gallon Plastic RV Water Tank (32.125" x 19.5" x 15.0")

Ronco has been molding the 1W since the mold library started growing in 1974, and the shape has stayed useful for a reason: 35 gallons in a 32.12 x 19.5 x 15 inch block that fits crosswise between the frame rails of a lot of coaches. It is the sort of tank you find when you pull a failed original out of an older motorhome and go looking for the same outline.

This is a light-duty potable molding - natural FDA-compliant polyethylene with a translucent wall, so a glance with a work light tells you how much water is aboard. Do not confuse it with the black-and-gray side of the catalog; fresh water tanks and holding tanks are different resins for different jobs.

Weight math worth doing before installation: the shell ships at 19 lb, but 35 gallons of water adds up to roughly 292 lb at 8.34 lb per gallon. If the 15-inch height will not clear, the RV2W carries the same 35 gallons at 12 inches tall; if you can go taller and shorter, see the RV34W at 33.5 x 19 x 16 inches. All the shapes are at RV water tanks. Print the drawing below, mark your fitting locations, and Ronco spin-welds or threads them in place per order at the Tustin, California plant.
