RV Water Tanks

Single-digit mold numbers are the old guard of Ronco's library, and the 5W is one of them - a 45-gallon fresh water shape that has been earning its tooling space in Tustin, California across five...

48 x 20 x 12 inches is a classic underfloor band: long enough to run between frame members, at 20 inches wide it drops between typical crossmember spacing, and 12 inches of height leaves room above...

Of Ronco's five 45-gallon fresh water moldings, the RV47W is the one you can plan around from your armchair: 36 x 23 x 13 inches, published. A compact block - three feet by two, just over a foot tall...

At 16 inches tall, the RV34W is the deepest of Ronco's 35-gallon fresh water moldings - a compact 33.5 x 19 inch footprint that goes vertical instead of sprawling. That geometry suits van conversions...

Water is the heaviest thing most RVs carry, and the RV28W's 55 gallons work out to about 459 lb at 8.34 lb per gallon - a payload worth planning around, which is why 55 has become such a common...

Second opinions matter when you are fitting a tank to a bay, and the RV32W is Ronco Plastics' second opinion at 55 gallons: same capacity as its sibling molds, its own geometry, a 74 lb light-duty...

46.75 x 20.75 x 15.5 inches - the RV42W's dimensions read like they were taken off a real chassis, because they were. Ronco Plastics molds five different 58-gallon fresh tanks, each shaped to a...

A 58-gallon tank that is also 58 inches long - the RV43W is easy to remember and easy to place: 58 x 20 x 13 inches, drawn long and low to run along a frame rail where taller tanks cannot go...

A perfect square, 34 x 34 inches, standing 13 low: the RV44W holds its 58 gallons in the footprint of a card table, which makes it the natural pick for basement bays and between-the-rails cavities...

Among Ronco Plastics' five 58-gallon fresh-water molds, the RV60W is the middle path: 44 x 22 x 15.5 inches - shorter than the rail-runner, longer than the square, at the full 15.5-inch height that...
