Ronco fields five different 45-gallon holding shapes - the deepest bench at any capacity in its waste line - and the 83H anchors it. Five molds at one volume is what almost fifty years of cutting coach-specific tooling since 1974 accumulates: at this size, the odds that one of them matches your cavity are very good.
The 83H itself is a 38 lb seamless rotomolded polyethylene shell, mid-weight for the group, carrying roughly 375 lb of gray or black water when full. Its outline is on the drawing below. Print it and check the fit; if it misses, work through the 87H, 105H, and 75H, or step down to the 44-gallon 96H. The full index is at RV holding tanks.
Whichever shape wins, the routine is the same: mark your drain, vent, and inlet locations on the printed drawing, and Ronco spin-welds or threads the fittings per order at its Tustin, California plant, so the tank arrives matched to your plumbing instead of the other way around. Waste duty only - fresh water rides in different resin.
