The RVB161 is Ronco Plastics' 28 gallon light-duty RV fresh water tank, shipping at 28 pounds. Twenty-eight gallons puts serious dry-camping range into a travel trailer or camper, and the tank is rotationally molded in Tustin, California, where Ronco has made polyethylene tanks since 1974.
Fresh water service calls for FDA-compliant natural polyethylene, which is exactly what the RVB161 is molded from; the translucent natural wall shows the water level directly, with no sender to drift or fail.
Ronco builds the connection layout you order, installing spin-weld or threaded fittings at customer-specified locations on this and every tank in its catalog. If a drawing accompanies the listing, it shows the blank molding. OneSource Plastics is an authorized Ronco Plastics dealer.
