Smallest of the line, the Ronco AD9412 packs 30 gallons of utility water into a 30 x 20 x 12 inch flat-bottom molding, listed on Ronco's sheet as the light-duty RVB157 blank. It is rotationally molded polyethylene, produced by Ronco Plastics at its Tustin, California plant, in operation since 1974.
Twelve inches tall and barely bigger than a cooler, this is the tank for the rig with no room to spare: a compact car detailing setup, a UTV bed, a small trailer, or a supplemental reserve tucked beside a larger tank. At roughly 250 pounds full, one person can still position it empty and fill it in place.
The drawing depicts the blank molding as it leaves the mold. When you order, Ronco installs spin-weld or threaded fittings wherever your plumbing requires them. OneSource Plastics is an authorized Ronco Plastics dealer.
