Ronco Plastics 76H - 11 Gallon End Dump RV Holding Tank (No Rails)

The 76H is the heavy one. Where most 11-gallon blanks come off the mold in the low teens of pounds, this tank ships at 32 lb - nearly three times the material of its sibling. That extra polyethylene goes into wall thickness, and thick walls are what you want when a waste tank hangs off a frame that sees washboard roads, or when the tank doubles as a step surface in a cramped utility bay.

For weight-sensitive builds, the 49H offers the same 11 gallons in a lighter molding. If the extra-rugged direction is right but you need more volume, look at long heavy blanks like the 44H, a 12-gallon tank stretched to 80.75 x 14 x 6.75 inches. Everything in between is in the RV holding tanks category.

Duty is waste only: gray or black water, no potable use ever. Full, plan on roughly 92 lb of contents on top of the 32 lb tank. See the rest of the line at the Ronco Plastics hub. One Source Plastics is an authorized Ronco Plastics dealer.
