At 30 x 12.5 x 7.25 inches, the 36H is what you spec when the waste tank has to share a bay with everything else: a 9-gallon holding tank barely more than seven inches tall, sized to slip under a floor or alongside a water heater where a full-height tank would never go.
Like every tank on Ronco's holding-tank sheet, it is for gray and black water only - no drinking-water rating, no crossover to the supply side. The 12 lb one-piece molding holds roughly 75 lb of waste at capacity, with the low, long profile keeping the plumbing drops short.
Since 1974, Ronco Plastics has rotomolded these in Tustin, California and installed every fitting per order, spin-weld or threaded, at the customer's marks. Print the drawing below and mark your fitting locations - inlet high, outlet low, vent where your stack runs - and the tank arrives ready. If you want the same capacity flatter and wider, take the 9-gallon 35H at 29.75 x 22.5 x 8 inches; for a longer, thinner ten, the 10-gallon 34H at 36 x 13 x 6 inches. The full family is under RV holding tanks.
