Ronco Plastics

Three gallons. The 13W is the smallest kind of honest: a 17 x 7 x 7 inch sleeve of polyethylene for the jobs where a big tank is the wrong answer - a camper van sink, a tool-trailer handwash station,...

Dump geometry is the quiet reason waste tank replacements go sideways, and it is the reason the 14H exists as a distinct 26 gallon molding. Its outlet is configured for an end dump, valve at the end...

At 8.25 inches tall, the 14W is a tank you install under things - under a bed platform, under a dinette, under the floor of a van where headroom is measured in fractions. The 24 x 15.5 inch footprint...

Ronco keeps four different 33 gallon holding tanks in production, and the 15H is the first stop in that family. Thirty-three gallons is fifth-wheel and Class A territory, the gray tank that has to...

Weight first: a full 16H carries about 158 lb of waste water. That number - not the 25 lb the empty blank weighs - is what your mounting hardware, straps, and floor structure have to be sized for,...

The 16W packs 11 gallons into 18 x 13 x 13 inches - the shortest footprint in its capacity class. Where its flat sibling spreads the same water across two feet of floor, this one stacks it into a box...

The Ronco 17H is a 25 gallon gray or black water holding molding, about 26 pounds empty and roughly 208 pounds full at 8.34 pounds per gallon, with no potable rating. It comes out of Tustin,...

The 17W is a pancake: 40.5 x 24 x 10 inches carrying 37 gallons. Ten inches of height is what lets a tank live under a bed platform, beneath a raised floor, or flat across trailer crossmembers...

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...

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...

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...

First in the catalog, and shaped like a workhorse: the 1W holds 35 gallons in a 32.12 x 19.5 x 15 inch block. These are the proportions of a tank that was never trying to hide - it wants a dedicated...
