A 40 gallon fresh water supply moves an RV from weekend range into serious dry-camping territory, and that is what the Ronco RVB221 provides. This light-duty polyethylene RV fresh water tank ships at 33 pounds, keeping installation a one-person proposition despite the capacity.
Molded for potable duty from FDA-compliant natural polyethylene, the RVB221 keeps the translucent wall common to Ronco fresh water tanks, so 40 gallons never becomes a guessing game; the waterline is visible through the plastic.
Like every Ronco molding it is produced by rotational molding in Tustin, California as a single seamless vessel, and finished with fittings installed per order: spin-weld or threaded, located wherever your specification puts fill, vent, and outlet. When a drawing is shown it depicts the blank molding. OneSource Plastics carries the RVB221 as an authorized Ronco Plastics dealer.
