Ronco Plastics Tanks

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,...

Twenty gallons is the most contested size in Ronco's holding line - the maker keeps roughly a half dozen distinct 20-gallon molds in production because that capacity maps to more RV floor plans than...

Five inches. That is the whole height of the 24H, and it is the reason this tank exists. Underfloor bays, basement compartments, and the gap between chassis rails on a lot of coaches will not take a...

Seventeen pounds. Among Ronco's crowded field of 20-gallon holding tanks, the 65H is the lightest blank - a full-size waste tank you can carry under one arm up a ladder into a mid-build coach. For...

A 22 x 22 inch footprint makes the 56H the square peg of Ronco's holding tank line, and sometimes a square hole is exactly what you have. Twelve inches deep, 21 gallons, with the dump outlet...

Here is the ordering ritual that makes a Ronco tank different from a parts-store tank, using the 17H as the example. You print the technical drawing from the block below this description. You take it...

The 62H is a square: 24.5 x 24.5 inches, 11.5 deep, 26 gallons. Square tanks exist because square holes exist, usually the bay left over between two frame members after everything else was packaged,...

Ronco's sheet rates the AD9401LD at a working 90 gallons even though the shell is the full 100-gallon, 38.5 x 26.5 x 25 inch auto-detail mold - the same body as the heavy-duty version, drawn in the...

Ronco's sheet entry for this tank reads 24W L.D., 31 gallons, 43 x 16 x 10.5, and the one-gallon gap with our 30 gallon listing is the honest kind: molded tanks are rated conservatively rather than...

On Ronco's own price sheet this tank is a terse line: "35W L.D. (13 GAL)". Decoded, that is the whole product - the 35W molding, light-duty potable spec, 13 gallons of fresh water. The L.D...

The 29H is the proportionate one: 16 gallons at 36 x 22 x 9.25 inches, a footprint close to a standard underfloor bay in mid-size travel trailers. No extreme dimension, no clever geometry - just a...

Twenty-six pounds of polyethylene for 17 gallons of capacity makes the 2H one of the stoutest builds in Ronco's mid-size holding range. That material ratio is the spec to notice: heavy walls resist...
