At 26 lb bare, the B429 is one of the easiest tanks in the series to actually install - 23 gallons of capacity in a shell light enough to hold overhead with one hand while you check clearances with the other. Refits are full of trial fits, and a tank you can move alone gets trial-fitted properly.
The light wall does not change the B-series formula: this is a dual-role molding that becomes a fresh water tank or a gray/black waste holding tank according to the fittings you order. Ronco installs them per order, spin-welded or thread-mounted at the positions you mark. Print the drawing below, mark your fitting locations, and run through the on-page fitting planner before you submit - moving a mark now is free, moving a welded fitting later is not.
Full, the 23 gallons weighs about 192 lb, so the shelf still needs to be real structure even if the tank is not heavy. Rotomolded in Tustin, California, where Ronco has made tanks since 1974. The boat tank category holds the neighboring sizes, and the complete line is on the Ronco Plastics hub. OneSource Plastics is an authorized Ronco Plastics dealer.
