Ronco Plastics Tanks in Tustin, CA

Sixteen inches tall. The AD9407 is the auto-detail tank you buy when the water has to ride under a tonneau cover, beneath shelving in a van, or below the bed rail where it cannot block the mirror...

Ronco's own price sheet calls this molding the 50W L.D. and rates it 27 gallons; we list it conservatively at 26. Either way, the story is the shape: 50 x 16 x 8 inches, a long low slab of fresh...

The RV71W and its sibling the RV50W hold the same fresh water two different ways, and choosing between them is pure geometry. This tank is the compact one: 38 x 20 x 9 inches, a foot shorter than the...

The RV26W is the dense option: 32 gallons of fresh water in a 31 x 23 x 11.5 inch block, the shortest footprint in a family whose other members stretch four and five feet. Compact tanks suit vertical...

The 57H solves the corridor problem: 16 gallons of holding capacity in a 63 x 10 x 8 inch run, a tank shaped like the space beside a driveshaft or along the outboard side of a frame rail. Ten inches...

On paper the 58H and its sibling are twins - both 16-gallon holding tanks, both 63 x 10 x 8 inches, both 19 lb blanks. The difference lives in the mold: each carries its own arrangement of molded...

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...

Twenty-six gallons in a 28-inch-long package: the 54H is the space-efficient member of its size class, a 28 x 22 x 11.5 inch box that fits compartments too short for the sprawling shapes. The blank...

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...

Start with the drawing on this one. The 104H comes from Ronco's newer 100-series molds, and if you are replacing a failed tank or designing a fresh bay, the dimensioned drawing below is the fastest...

A black-tank replacement is the classic job for the 94H. Seventeen gallons matches the toilet waste capacity of a wide band of travel trailers from the last few decades, and when the original tank...
