Three gallons, seventeen inches long, six pounds on the shipping scale. The RV13W is the smallest fresh water tank Ronco Plastics molds in the RV W-series, and it is the right size for exactly the installs where nothing else fits: teardrop galleys, van bench seats, truck camper nooks, a dedicated supply for a cassette toilet or an outdoor rinse station. At 17 x 7 x 7 inches it slides into a shoebox of space and holds about 25 pounds of water when full, little enough that you can mount it high without engineering around it.
The molding is FDA-compliant natural polyethylene, translucent enough to read the water level through the wall, rotomolded in one seamless piece at Ronco's Tustin, California plant the same way they have built RV tanks since 1974. Fill high or fill low, vent where your run needs it, outlet sized to your pump.
If three gallons is tighter than your build, the W-series steps up smoothly: the 11 gallon RV23W, the cube-ish RV16W at 18 x 13 x 13, and the shallow RV14W cover the next bracket, and the whole run to 95 gallons lives in RV water tanks. One Source Plastics is an authorized Ronco Plastics dealer.
