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.
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. One Source Plastics is an authorized Ronco Plastics dealer.
