The RVB455 is the rare B-series tank that leads with its dimensions: 44 x 24 x 24 inches, 100 gallons, from Ronco's own maker sheet. That near-square cross-section is the whole personality of the tank - it packs maximum volume into a compact rectangular block instead of a long, low slab, which suits basement bays and cargo-area corners where length is the scarce resource and there is height to spare.
It is a light-duty potable molding in translucent natural polyethylene, 115 pounds as shipped, FDA compliant for drinking water. Like every tank Ronco has molded in Tustin, California since 1974, the wall is translucent enough to read the water level directly - and on a block this tall, that vertical water line is an unusually precise gauge.
A full 100 gallons weighs serious money at 8.34 pounds per gallon, and a tall tank concentrates that load on a smaller base than a low-profile shape does, so give it a continuous, structural floor. Fittings are installed per order - spin-welded or threaded to your marks - which on a cube-ish tank means real freedom: ports can go on whichever face your plumbing prefers. Print the technical drawing below, mark it, and finalize with the fitting planner on this page.
If the bay wants a different geometry, the RV water tank family runs from compact sizes up, the Ronco Plastics hub shows every shape, and the freight estimator prices the trip to your door. OneSource Plastics is an authorized Ronco Plastics dealer.
