Ronco's RVB158 is a light-duty 36 gallon RV water tank for potable fresh water, with a shipping weight of 33 pounds. A 36 gallon supply keeps showers, dishwashing, and drinking water going for days on a mid-size rig, making it a solid upgrade target when a factory tank feels too small.
The material is FDA-compliant natural polyethylene, chosen for drinking water contact, and its translucent finish lets the water level show through the tank wall wherever the tank is visible in its bay.
Each RVB158 is rotationally molded as one seamless piece by Ronco Plastics in Tustin, California, a shop molding tanks since 1974. Ronco installs fittings per order, locating spin-weld or threaded fittings to the customer's specification before shipment, standard on every tank; when a drawing is shown it depicts the blank molding.
