At 25 lb for 42 gallons of capacity, the 74H is the lightest shell in Ronco's 42-gallon holding quartet - the pick when the tank rides in a supported cradle or framed compartment and the installer would rather not wrestle extra weight under a coach on jack stands. Full, it holds roughly 350 lb of gray or black water in one seamless rotomolded polyethylene piece.
Shape selection runs through the drawings. Print the 74H sheet below and lay its outline against your cavity; if it misses, the 61H offers the same capacity with a side dump at 45 x 24.5 x 12 inches, while the 21H and 106H carry their own outlines. A gallon up sits the 43-gallon 88H.
Whichever wins, mark your fitting locations on the printed drawing - Ronco molds every tank blank and spin-welds or threads the drain, vent, and inlet per order at its Tustin, California plant, a make-to-marks service running since 1974. Waste duty only, never potable; browse the rest at RV holding tanks.
