RV Water Tanks

Mold number 4W is one of the low numbers in Ronco Plastics' fresh-water book, and low numbers mean longevity: this 60-gallon shape has been earning its keep since the era when Ronco - rotomolding in...

Ninety gallons in a slab: the RV64W measures 39.25 x 39.25 inches square and only 14.5 inches tall, which is how Ronco Plastics gets big-rig water capacity under a floor instead of inside a closet...

The RVB295 holds 52 gallons and ships at 41 lb - a light-duty fresh water molding, listed by Ronco as the B-295 L.D., with one of the best water-to-tank-weight ratios in the book. Every pound of tank...

The RVB546 is Ronco Plastics' heavy-shipping 25 gallon light-duty RV fresh water tank, weighing in at 84 pounds on the freight scale. It is rotationally molded in Tustin, California at a plant that...

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...

The jump from the 50s and 60s to the RV61W's 75 gallons is the jump from weekend range to expedition range - and the mold makes that volume surprisingly easy to package at 54 x 22 x 16 inches, a long...

Ninety gallons at 60 lb of tank: the RVB314 - Ronco's B-314 L.D. - is the big light-duty molding for coaches that want serious dry-camping range without stepping up to the expedition monsters. Ninety...

Full-timers and long-range boondockers size their fresh water around 50 gallons, and the Ronco RVB416 is molded for exactly that duty. A light-duty potable water tank for RV service, it ships at...

Measure the bay before you fall in love with any tank. That is the RVB466's honest sales pitch: it is a large light-duty fresh water molding in Ronco's B-series - 124 pounds of translucent natural...

The number that makes the RVB401 interesting is not the 70 gallons - it is the 52 pounds. Most B-series tanks in this capacity class weigh twice as much; this molding puts a genuinely useful fresh...
