Where most 22 gallon holding tanks spread out, the 53H digs down: 30 x 22 inches of footprint and a full 13.5 inches of depth, the deepest shape in Ronco's 22 gallon family. That geometry suits compartments that are short front-to-back but have vertical room, and the added depth improves drain-down toward a bottom outlet compared with the pancake shapes.
Service is gray or black water only, never potable. The molding runs about 22 pounds empty and carries roughly 183 pounds when its 22 gallons are full at 8.34 pounds per gallon. If your cavity wants a different envelope with the same capacity, the 10H goes longer and shallower at 34 x 22 x 12 and the 28H goes narrow at 53 x 11.25 x 12; one size down, the 56H end-dump is a 22 x 22 x 12 square.
The complete lineup is at RV holding tanks. One Source Plastics is an authorized Ronco Plastics dealer.
