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 polyethylene - and whether it belongs in your build is decided entirely by the technical drawing below, not by marketing copy. Print it. Take a tape to the compartment: clear opening, floor length and width, height under obstructions, the path from the door to the final resting spot. If the drawing clears all four, you have found your tank.
The spec is Ronco's standard for potable service: FDA-compliant resin, natural translucent finish that shows the water level through the wall, light-duty wall schedule matched to supported in-vehicle installation. The Tustin, California plant has been molding this family since 1974, so dimensional consistency from the drawing to the delivered part is the norm, not the hope.
Fittings are the second decision. Ronco spin-welds or threads every port per order at the locations you mark, so the same drawing you used to qualify the bay becomes your fitting map - lay out fill, vent, and supply on it, then confirm the whole layout in the fitting planner on this page. Budget the loaded weight while you are at it: water is 8.34 pounds per gallon, and big tanks earn structural mounting.
