RV Holding Tanks

Thirteen gallons is an honest weekend of gray water for two people, and the 26H is Ronco's compact way to carry it. At 16 lb out of the mold it is an easy tank to handle solo through a retrofit, and...

Fourteen gallons is where a holding tank stops being a day tank and starts covering a real trip: enough gray water margin for several days of dishes and quick showers for two. The 40H hits that mark...

The Todd Marine 20-gallon marine water & holding tank (85-1666WH) is a one-piece rotationally molded polyethylene tank engineered for potable water storage or waste holding aboard boats and RVs. The...

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...

The 100H is the tank you buy when the holding tank that died was an odd one. Ten gallons is the working size for pop-ups, truck campers, and small travel trailers, and Ronco Plastics molds a whole...

The 12H goes deep instead of wide: 18 gallons in a 22 x 23 x 12.5 inch cube, the deepest draw in its capacity class. A tank like this occupies a compact square of floor - barely two feet on a side -...

The Todd Marine 25-gallon marine water & holding tank (85-1532WH) is a one-piece rotationally molded polyethylene tank engineered for potable water storage or waste holding aboard boats and RVs. The...

Every catalog starts somewhere, and Ronco's starts here: the 1H, part number one, a 20-gallon holding tank that has been in the line since the Tustin, California shop began rotomolding in 1974. Molds...

The 35H is a pancake: 9 gallons of holding capacity rolled out to 29.75 x 22.5 inches but standing just 8 inches tall. Ronco Plastics draws it this way for underfloor waste service where the frame...

Nearly seven feet of tank. The 44H runs 80.75 x 14 x 6.75 inches - a 12-gallon holding tank stretched into a beam that lays along a frame rail or under a full-length slide floor where nothing...

Ronco molds four different 15-gallon holding tanks, and the 18H is the general-purpose one - the blank you choose when no single dimension of your bay is doing anything unusual. At 16 lb empty it...

A black-tank replacement is the classic job for the 94H. The 94H ships at 23 lb and holds about 142 lb of waste at full. Gray or black water only; it carries no potable rating. If your measurements...
