The Ronco RVB525 holds 4.25 gallons, a light-duty potable water tank at the very compact end of the RV range. Shipping at 13 pounds, it serves teardrops, truck campers, van sinks, and auxiliary points of use where a full-size fresh tank is overkill and space is measured in inches.
Being a fresh water tank, it is molded of FDA-compliant natural polyethylene. Translucence comes with the natural resin, so even this small vessel shows its level through the wall, which spares you opening a cap to check a few gallons.
Rotational molding at Ronco Plastics in Tustin, California, where tanks have been made since 1974, forms the RVB525 as one seamless piece. Ronco installs fittings per order, spin-weld or threaded, at the customer's specified locations, its standard on all tanks; drawings shown depict the unfitted molding.
