Ronco's RVB408 delivers 25 gallons of light-duty fresh water capacity for RVs at a 30 pound shipping weight. Molded rotationally by Ronco Plastics in Tustin, California, a polyethylene tank maker since 1974, it fits travel trailers, slide-ins, and van conversions that need real dry-camping range.
It is a potable-side tank, so the resin is FDA-compliant natural polyethylene; the wall's translucency doubles as a level indicator, showing how much water remains without electronics.
Ronco's standard build-to-order fitment means spin-weld or threaded fittings are installed at the points your specification defines, on every tank; a drawing, if shown, depicts the blank molding. OneSource Plastics supplies the RVB408 as an authorized Ronco Plastics dealer.
