Start with the arithmetic: 60 gallons of waste water weighs about 500 lb. That number, not the gallon figure, is what the 82H asks of your coach - a quarter ton of sloshing load that has to ride on structure. The tank itself contributes only 90 lb empty, honest rotomolded polyethylene with the mass where it belongs, in the wall.
Sixty gallons is full-timer capacity. It roughly triples the dump interval of the 20-gallon class tanks that production trailers ship with, which is the difference between planning a trip around dump stations and simply going. Boondockers and bus converters are the natural buyers here.
The 82H comes out of Tustin, California, where Ronco has rotomolded tanks since 1974, and like all of them it ships as a drilled-to-order blank: spin-weld or threaded fittings installed wherever you mark them. Print the drawing below and mark your outlet, inlet, and vent - or drop them on the on-page fitting planner. Need a different footprint at similar volume? The 92H carries 48 gallons and the 96H carries 44; the complete spread is in the RV holding tank category. OneSource Plastics is an authorized Ronco Plastics dealer.
