The 62H is a square: 24.5 x 24.5 inches, 11.5 deep, 26 gallons. Square tanks exist because square holes exist, usually the bay left over between two frame members after everything else was packaged, and when that is your hole, no amount of shopping rectangular tanks will save you. At about 20 pounds empty, it is also an easy molding to dry-fit single-handed.
Duty is strictly waste: gray or black water, no potable rating. The full-load figure to design around is about 217 pounds, which is 26 gallons at 8.34 pounds per gallon, cycling from empty to full and back every trip. If the square footprint is close but wrong, the 54H rearranges the same 26 gallons into 28 x 22 x 11.5 and the 14H brings end-dump plumbing with molded rails.
Ronco Plastics has rotomolded in Tustin, California since 1974, and finishes every tank with fittings installed per order, spin-welded or threaded at your marked positions. The drawing block below prints at scale; mark inlet, outlet, and vent where your plumbing actually runs, or click them into the fitting planner, and Ronco builds that tank. The rest of the line is under RV holding tanks and the Ronco Plastics hub. OneSource Plastics is an authorized Ronco Plastics dealer.
