Ronco RV Holding Tanks

The 46H spends its 13 gallons on area instead of depth: a 52 x 30 inch slab standing only 8 inches tall. That two-and-a-half-foot width is unusual in the holding line and it exists for wide, shallow...

Pick the 99H up before you judge it. At roughly 44 pounds, this blank carries about twice the polyethylene of most 22 gallon holding tanks in Ronco's line, which tells you where it came from: an...

The 37H is a 36-gallon gray/black holding tank, and like most of Ronco's waste line its exact outline lives on the technical drawing rather than in a headline dimension - print the drawing below, lay...

Fifty-six and a half inches long, 19 wide, 12.5 tall: the 5H is the long-and-lean take on a 40-gallon waste tank, drawn to run lengthwise along a frame rail where a wide pan will not clear the...

Forty-eight gallons puts the 60H at the big end of Ronco Plastics' RV holding-tank line, and the family around it is worth a look before you commit: the 48-gallon 92H holds the same volume in a...

Thirty-eight inches long, 8.12 inches tall: the 20W is a plank of a tank. It runs 17 gallons out along a chassis rail or under a bunk in a strip 15.5 inches wide, thin enough to disappear beneath a...

Under eight inches tall. The 72W closes out the slice at 35 x 19 x 7.75 inches, putting 19 gallons into one of the thinnest profiles Ronco molds. This is the tank for the layer nobody sees: between a...

Six and a half feet of tank, eight and a half inches of height: the Ronco Plastics B310 is the B-series at its most extreme - 45 gallons stretched across 78" x 18" x 8.5" to run the full length of a...

The Ronco Plastics B318 is the generalist of the mid-size B-series: 45 gallons at 40" x 19" x 15.62", proportions that fit under berths, behind settees, and across RV bay floors without demanding a...

Narrow spaces get their own tank: the Ronco Plastics B312 runs 72" x 15" x 13", a six-foot rail of a molding that carries 53 gallons along a keel line, a chassis frame run, or the slot behind a rear...

The Ronco Plastics B315 concentrates 52 gallons into a 30.5" x 24.38" x 17.38" block that weighs just 41 lb empty - a capacity-to-weight ratio that makes it one of the easiest big tanks in the...

The 60W is the crossover big tank: 58 gallons at 44 x 22 x 15.5 inches, cataloged for RV and marine service in the same breath. Coach builders stand it in a basement bay; boatbuilders lay it beneath...
