The Ronco RVB409 is a light-duty 33 gallon plastic RV water tank for potable fresh water, shipping at 77 pounds. For a mid-size travel trailer or camper van with serious water needs, 33 gallons covers drinking, dishes, and quick showers across a multi-day stretch away from hookups.
Potable duty is built into the material: FDA-compliant natural polyethylene, rotationally molded into a seamless one-piece tank at Ronco Plastics in Tustin, California. The natural resin is translucent, so the tank wall itself shows you the water level from full to empty.
Fitting placement follows your order, not a template. Ronco locates spin-weld or threaded fittings to each customer's specification and installs them before the tank leaves the plant, standard for every tank in the line; drawings, when shown, depict the blank molding.
