The B450 is the slim sibling in Ronco's long-tank family: 23 gallons at 44.5 x 12.5 x 11.5 inches, a cross-section barely a foot square stretched to nearly four feet. When the only unclaimed space aboard is a narrow run - beside a fuel tank, along a frame rail, under the edge of a bunk flat - this is the molding shaped for it.
Marine or RV, the shell is dual-role: fresh water with potable fittings, gray/black holding with waste fittings, and Ronco installs whichever set you order at the positions you mark, spin-welded or threaded. On a long narrow tank the fittings can go almost anywhere along the run, so print the drawing below, mark them where your hoses genuinely arrive, and confirm the sizes with the on-page fitting planner.
It ships at 79 lb and carries about 192 lb of water when full. Molded in Tustin, California by Ronco, in the rotomolding trade since 1974. A wider version of this format and the rest of the narrow tanks are in the boat tank category; RV-oriented shapes are under RV water tanks and RV holding tanks.
