Eighteen gallons of drinking water, 23 pounds of tank: the Ronco RVB527 is a light-duty polyethylene RV water tank for trailers and camper conversions that want extended fresh capacity without a bulky vessel dominating the bay.
Every RVB527 comes from Ronco Plastics' rotational molding plant in Tustin, California, an operation making polyethylene tanks since 1974, and leaves the plant with its ports already installed. Ronco locates spin-weld or threaded fittings to the customer's specification on each order, standard across the whole Ronco line; drawings shown depict the blank molding before that step.
Materially it is a proper potable tank, FDA-compliant natural polyethylene throughout, with a translucent wall that lets the water level show through so you always know where your supply stands. OneSource Plastics supplies the RVB527 as an authorized Ronco Plastics dealer.
