At 47 lb of bare shell, the 85H is the heaviest molding among Ronco's 36-gallon holding tanks - noticeably more polyethylene than the 32 lb 37H or the 27 lb 48H at the same capacity. When a tank hangs from underfloor straps and carries 300 lb of waste over washboard roads for years, that extra material is exactly where you want it.
All three 36-gallon shapes serve the same job - gray or black water, never potable - so the pick comes down to cavity fit and construction. The 48H measures 35 x 25 x 12.75 inches; the 37H and this 85H are drawn on their technical sheets. Print the 85H drawing below and check the outline against your frame before ordering. Nearby capacities include the 37-gallon 73H and the 35-gallon 101H.
Like every tank in the holding line, the 85H is molded blank in Tustin, California - one seamless rotomolded piece, no factory holes - and fitted per order. Mark drain, vent, and inlet locations on your printed drawing and Ronco spin-welds or threads them exactly there, the same custom-fit service the shop has offered since 1974.
