The Ronco Plastics B404 is a 6 gallon square-footprint molding, 13.75 x 13.75 x 10 inches, shaped to occupy a single locker corner or console void. Ronco lists it for water or waste because the B-series shell truly does both: order potable fittings and the food-grade polyethylene carries drinking water; order waste fittings and it collects gray water from a head or galley sink.
Handling is effortless at 11 lb empty and about 50 lb full at 8.34 lb per gallon. Simple straps over a flat base are all the mounting it needs.
Fittings are installed per order, spin-welded or threaded exactly where you mark them, so even in a cramped corner the connections land where hoses can actually reach.
