Somewhere there is a fifth wheel sitting dead in a storage yard because its 33 gallon gray tank split and the manufacturer went under in the last downturn. The 79H is the kind of molding that revives it.
The tank is a 33 gallon gray or black water molding, about 29 pounds empty, no potable rating, with a full-load weight around 275 pounds at 8.34 pounds per gallon. Identification is by measurement: check your cavity against this tank's drawing, then against the 52H at 46 x 16 x 12.75 inches, the 15H, and the heavy-wall 68H, the other three shapes in the size.
The complete range is under RV holding tanks. One Source Plastics is an authorized Ronco Plastics dealer.
