The Ronco Plastics B302 is a 210-gallon fresh water tank in a 60" x 36" x 24" block - water-hauler scale, built for large coaches, utility trailers, and off-grid supply runs where the tank is the point of the trip. The proportions balance capacity against handling: wide and only 24" tall, it keeps its roughly 1,751 lb full-load low and spread across the frame. Empty, the molding weighs 158 lb.
Everything about a tank this size rewards planning, and Ronco's build-to-order fittings are the tool for it. Each spin-weld or threaded fitting goes in at your marked location - a wide gravity outlet for fast dumps, a pump pickup at the true low corner, a generous fill and high vent for fast, airlock-free loading. Print the drawing below, lay out the ports against your rig, and let the on-page fitting planner check the spec before you order. FDA-grade polyethylene keeps the load potable, whether it feeds a coach or a cabin cistern.
Ronco Plastics has molded bulk water tanks in Tustin, California since 1974, and the B302 is among the largest formats in our RV water tanks collection. It travels by freight - price your ZIP with the freight cost estimator - and the full Ronco Plastics catalog holds the rest of the heavy hitters.
