Ronco Plastics Tanks in Tustin, CA

Three gallons, seventeen inches long, six pounds on the shipping scale. The RV13W is the smallest fresh water tank Ronco Plastics molds in the RV W-series, and it is the right size for exactly the...

Nine inches wide. That single dimension is why the 9H exists: a 7-gallon holding tank drawn out to 30 x 9 x 11.25 inches so it can slide into a chase, a rocker cavity, or the gap beside a frame rail...

Ronco Plastics molds two different 7-gallon RV holding tanks, and the 19H is the one you buy when the other shape loses. The 7-gallon 9H measures 30 x 9 x 11.25 inches - long and narrow; the 19H is a...

Seven pounds. The RV41W is light enough to hold with one hand while you test-fit it in a gear locker, which is exactly how most of these get bought: an 8-gallon fresh water tank at 17 x 12.75 x 10...

Ronco's maker sheet calls the RV11W "11W L.D. (14 GAL) 21X13X13" - fourteen gallons of fresh water in a 21 x 13 x 13 inch near-cube. That tall, short-footprint geometry is the point: it drops into a...

At 30 x 12.5 x 7.25 inches, the 36H is what you spec when the waste tank has to share a bay with everything else: a 9-gallon holding tank barely more than seven inches tall, sized to slip under a...

Ten inches wide. The RV23W is Ronco's answer to the space between frame rails: an 11-gallon fresh water tank drawn out to 30.25 x 10 x 9 inches so it drops into chassis channels and narrow benches...

Most fresh water tanks sprawl; the RV16W stacks. At 18 x 13 x 13 inches it is the closest thing in Ronco's water line to a cube - 12 gallons of potable capacity standing in a footprint barely larger...

Under a bunk, under a dinette seat, under the floor of a van - the RV14W is the tank you slide beneath things. Its 12 gallons ride in a 24 x 15.5 x 8.25 inch slab, low enough to disappear under a...

Ronco molds the 14-gallon fresh water tank in three distinct bodies, and the RV3W is the slender one: 29.75 x 13.88 x 8.12 inches, sized for the narrow gap between a wheel well and a cabinet base...

Where most small fresh tanks go tall, the RV21W goes flat: 8 gallons spread across 17.75 x 15.75 inches while standing only 8.25 inches high. That squat, nearly square footprint is built for...

On Ronco's own price sheet this mold is the 56W, stamped at a conservative 7 gallons; we catalog it at the 9 gallons it actually holds. Either way the geometry is the selling point: 20.5 x 12.75 x 8...
