Eighty-three inches. The 33H is nearly seven feet of holding tank, 13.5 inches wide and 10 deep, molded for the space almost no replacement tank fits: the long run between frame rails under a coach floor. It actually holds 23 gallons, and if your dead tank is a long skinny extrusion of a thing that no parts catalog seems to carry, this molding and its shorter cousin the 28H at 53 x 11.25 x 12 inches are the two candidates to measure against.
It is a waste tank for gray or black water service, with no potable claim, and the length changes the engineering conversation: 23 gallons at 8.34 pounds per gallon is about 192 pounds distributed across a seven-foot span, so support it along the run, not just at the ends. The blank itself weighs about 30 pounds.
Ronco has molded RV tanks in Tustin, California since 1974, and every tank gets its spin-weld or threaded fittings installed to the customer's marks, which matters doubly on a tank this long, because where along those 83 inches the outlet lands is everything. Print the drawing below and mark your fitting locations on it before you order. If the proportions are close but not right, try the 10H box at 34 x 22 x 12 or the 24 gallon 67H, all under RV holding tanks. OneSource Plastics is an authorized Ronco Plastics dealer.
