Ronco part RVB147 is a 35 gallon light-duty plastic RV water tank for potable fresh water, shipping at 85 pounds. In practical terms, 35 gallons keeps a two-person rig self-sufficient for several days of dry camping before the fresh side needs a refill.
The tank is made the way Ronco Plastics has made tanks in Tustin, California since 1974: rotationally molded in one piece from FDA-compliant natural polyethylene. That resin choice covers drinking water contact, and its translucence turns the tank wall into a level gauge you read directly.
No fixed port pattern here. On each order Ronco installs spin-weld or threaded fittings located to the customer's specification, which is standard across all Ronco tanks; when a drawing is shown, it depicts the blank molding before fittings are added. OneSource Plastics offers the RVB147 as an authorized Ronco Plastics dealer.
