The Ronco RVB510 delivers 42 gallons of fresh water capacity at a 35 pound shipping weight, a strong capacity-to-weight combination among light-duty RV tanks. It stores potable water for motorhomes, fifth wheels, and trailers built for longer runs between hookups.
Forty-two gallons is real endurance: paired with sensible use, it can carry a couple through a week of drinking, cooking, and washing. The FDA-compliant natural polyethylene wall is translucent, so you can watch that supply drop day by day and plan the next fill accordingly.
Ronco Plastics rotationally molds the RVB510 in Tustin, California as one seamless vessel and installs fittings per order, its standard across the line: spin-weld or threaded fittings located exactly where your specification calls for them.
