Measure your bay first: if you have 35 inches of length, 25 of width, and 12.75 of height, the 48H puts 36 gallons of waste capacity in it. This is the fully-dimensioned member of Ronco's 36-gallon holding trio - a compact, blocky footprint rather than a long shallow pan, suited to coaches that concentrate their plumbing in one deep cavity.
Full, it carries about 300 lb of gray or black water; empty, the seamless rotomolded polyethylene shell is a 27 lb one-person lift. If your space runs shallower and wider, the 35-gallon 3H spreads out at 64 x 32 x 8 inches; if it is the same capacity in a different block, compare the 37H and 85H drawings. The 39-gallon 55H at 49 x 24 x 10 inches is the next step up with published dimensions.
The 48H arrives with no pre-cut holes - your drain, vent, and inlet go where your plumbing dictates. Print the drawing below, mark your fitting locations, and Ronco's Tustin, California crew spin-welds or threads them in per order, as they have on RV tanks since 1974. Waste duty only; see the fresh water tanks for potable service.
