Ronco RV Holding Tanks

The Ronco Plastics B163 is 25 gallons kept deliberately low: 30 x 20 x 10 inches, a footprint that slips under bunks, cockpit soles, and camper floors where every vertical inch is contested. It comes...

Eight inches of height is all the Ronco Plastics B378 asks. This 23 gallon B-series molding spreads its capacity across a 40 x 18 x 8 inch pancake profile, sliding under floors, berths, and dinette...

The B446 is another of Ronco's floor tanks: 24 gallons in a 44 x 26 x 6 inch slab. Six inches of height means it lives where furniture and floors already are - under a dinette, beneath a raised van...

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...

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...
