The B430 is a tube of a tank: 22 gallons stretched into a 45.5 x 11.5 x 11.5 inch section that runs along a stringer, down the side of an engine bay, or through the narrow chase under an RV floor where nothing squarer will pass. Long-and-slim is the shape that finds capacity in boats and coaches that look like they have none left.
Like every B-series shell it is dual-role - fresh water with potable fittings, gray/black holding with sanitation fittings - and Ronco builds it to order rather than to a fixed pattern. With this much length you have real freedom in where the fittings land, so print the drawing below, mark inlet and outlet where your plumbing actually arrives, and let the on-page fitting planner confirm sizes. Spin-weld or threaded, they go exactly on your marks.
The blank ships at 78 lb and carries about 183 lb of water when full, spread usefully along its length. Molded in Tustin, California by Ronco, rotomolding since 1974. Compare other narrow formats in the boat tank lineup and the RV water tank lineup. OneSource Plastics is an authorized Ronco Plastics dealer.
