Ronco Plastics RV12W - 43 Gallon Plastic RV Water Tank

Forty-three gallons is boondocking range. It is dishes, showers, coffee, and dog bowls for a long weekend without a hookup, and the RV12W is the light-duty Ronco W-series molding that carries it. This is a tank for full-size travel trailers and fifth wheels, replacing the factory fresh tank that cracked at a baffle or never held enough in the first place. Plan the mounting around the load: 43 gallons of water is roughly 359 pounds, so it belongs on frame rails or a supported floor, mounted low.

Ronco has rotomolded RV water tanks at its Tustin, California plant since 1974, and this molding follows the W-series pattern: seamless FDA-compliant natural polyethylene, translucent so a flashlight shows your remaining water at a glance, shipped as a 76 pound blank with no ports. The ports come from you. Ronco spin-welds or threads fittings at the locations you mark, which for a big fresh tank matters twice: the fill needs to land where your gravity fill or city-water plumbing already runs, and the outlet needs to feed your pump from the true low corner of your specific mounting angle.

Print the technical drawing from the link below, mark those locations, and order to the marks. If 43 gallons overshoots the space, the mid-size W-series brackets it with the 14 gallon RV37W and 13 gallon RV35W, and the top of the family is the 95 gallon RV66W; the full spread is in RV water tanks. Freight on a tank this size is quoted live to your ZIP with the freight estimator. OneSource Plastics is an authorized Ronco Plastics dealer.
