The 37H is a 36-gallon gray/black holding tank, and like most of Ronco's waste line its exact outline lives on the technical drawing rather than in a headline dimension - print the drawing below, lay it against your bay, and you will know in two minutes whether this is your tank.
Thirty-six gallons full means roughly 300 lb of waste, held in a single seamless rotomolded polyethylene shell that ships at just 32 lb. There are two other 36-gallon shapes in the library if this one does not fit: the 48H, a known quantity at 35 x 25 x 12.75 inches, and the 85H. One gallon either side sit the 35-gallon 3H at 64 x 32 x 8 inches and the 37-gallon 66H.
Every shell comes out of Ronco's Tustin, California plant, where the mold count has been growing since 1974 - which is exactly why odd, coach-specific shapes like this still exist at all. Waste service only, gray or black water; potable duty belongs to the separate fresh water line.
