Less than 5" tall and nearly 3 feet long, the Ronco Plastics B319 is a floor tank in the most literal sense: 11 gallons spread across 35" x 19.5" x 4.75", thin enough to disappear beneath a van floor, a berth platform, or a cockpit sole with clearance to spare. Capacity this flat is found, not made - the space it uses was doing nothing. The molding ships at 22 lb and holds about 92 lb of water when full.
It is a dual-purpose marine and RV molding, finished as a fresh water tank or a gray or black waste holding tank by the fittings you order. At 4.75" of depth there is no margin for a misplaced port: the outlet must sit at the exact low corner of the installed pitch or water strands beyond reach. Ronco installs each spin-weld or threaded fitting at your marks - print the drawing below, check your floor's true slope, and confirm the locations with the on-page fitting planner. Fresh-service builds use the FDA-grade polyethylene for a fully potable supply.
Ronco Plastics has molded ultra-low-profile tanks in Tustin, California since 1974. The rest of the thin family lines our boat tanks shelf, with coach-side equivalents under RV water tanks and RV holding tanks. OneSource Plastics is an authorized Ronco Plastics dealer.
