Ronco Plastics 59H - 10 Gallon Plastic RV Holding Tank (28.0" x 14.5" x 11.0")

The 59H packs 10 gallons of waste capacity into a 28 x 14.5 x 11 inch envelope, which makes it one of the shortest holding tanks Ronco molds: at 28 inches end to end it clears bays that a standard 36-inch blank simply cannot enter. The trade is height. At 11 inches deep it wants vertical room under the floor, so measure your bay depth before you measure anything else.

If the bay runs long and shallow instead, the same 10 gallons is available flipped the other way: the 34H holds 10 gallons in a 36 x 13 x 6 inch low-profile molding. Going smaller, the 9H is a 7-gallon tank at 30 x 9 x 11.25 inches for van and truck-camper conversions. The full range of shapes lives in our RV holding tank category.

This is a waste tank for gray or black water only - it is not a potable molding, so never plumb it as fresh supply. Full, it carries about 83 lb of waste water, so support the floor of the tank, not just the flanges.
