The B245 is the tank you spec when the space is small but the need is real: 14 gallons in a 24.5 x 16.5 x 9.12 inch box that tucks under a dinette seat, a cockpit locker shelf, or a van conversion's bench. Under two feet in its longest dimension and just 19 lb empty, it is a one-person install from carry-in to strap-down.
What it becomes is up to your fitting order. This is a B-series dual-role molding: mark it for supply and the food-grade polyethylene carries potable fresh water; mark it for waste and it holds gray or black water in exactly the same envelope. It ships blank - print the drawing below, mark your fitting locations, and the on-page fitting planner specs the spin-weld or threaded hardware Ronco installs to your marks.
Full, it carries about 117 lb, so give it a solid floor and a strap even at this size - water always finds the loose tank in a seaway or on a washboard road. Rotomolded in Tustin, California since 1974. Fit it into the bigger picture via our boat tank category, RV water tanks, or the full Ronco Plastics hub. OneSource Plastics is an authorized Ronco Plastics dealer.
