Eighty gallons of fresh water is the difference between a weekend hop and a real cruise, and the Ronco Plastics B367 packs exactly that into a single rotationally molded shell. It is a B-series marine molding, which means the same tank can be plumbed as a potable fresh water tank or as a gray or black waste holding tank; the role is set entirely by the fittings you order, not by the shell itself. Specified for fresh water, the food-grade polyethylene is safe for drinking water systems.
Plan your capacity honestly: 80 gallons of water weighs about 667 lb at 8.34 lb per gallon, so mounting location and support matter as much as the tank itself. The bare molding ships at 124 lb.
Every B367 leaves the shop with fittings installed per order, spin-welded or threaded exactly where you mark them. Print the drawing below, sketch your inlet, outlet, and vent positions, and use the fitting planner on this page to build the spec. Ronco has been molding tanks in Tustin, California since 1974, and this made-to-order fitting work is the reason boatbuilders keep coming back.
