Ronco molds four different 35-gallon holding tanks, and the reason is simple: no two coach floors are framed alike. The 90H is one of those four shapes - same 35-gallon capacity, its own footprint. Before ordering, print the drawing below, check the outline against your bay, and mark your fitting locations right on the sheet.
If the 90H's shape is close but not right, compare its three capacity twins: the 3H, a wide shallow pan at 64 x 32 x 8 inches, the 4H with side dump at 53.75 x 25 x 8 inches, and the 93H. All four hold the same 292 lb of waste when full; the only question is which outline your frame rails accept. The complete range is on the RV holding tanks page.
Like every Ronco waste tank, the 90H is a one-piece rotational molding in waste-duty polyethylene - a 29 lb blank shell with no seams and no factory-placed holes. Fittings are installed to your marks per order, spin-welded or threaded, at the Tustin, California plant where Ronco has molded tanks since 1974. Gray or black water service only; this resin and construction are not for potable use.
