A 39 lb molding that will carry roughly 400 lb of waste: that ratio is the whole argument for rotomolded polyethylene, and the 92H is Ronco Plastics' 48-gallon RV holding tank in one of two shapes they mold at this capacity. The other is the 48-gallon 60H; if neither profile works, the 50-gallon 91H sits just above and the 47-gallon 97H just below.
Holding-tank duty means gray and black water only. The resin and wall spec are chosen for waste service, not potable supply, and no drinking-water claim applies. What the spec does buy you is a seamless one-piece shell with no weld lines to weep under a coach that gets towed down washboard roads.
Because Ronco installs fittings per order at the Tustin, California plant it has run since 1974, the tank you receive is drilled and fitted to your layout rather than a guess at it. Print the drawing below, mark your fitting locations for the spin-weld or threaded fittings you need, and compare footprints across the full RV holding tank range or the whole Ronco Plastics line.
OneSource Plastics is an authorized Ronco Plastics dealer.
