The B433 is the capacity king of Ronco's RV-format water tanks: 110 gallons in a 48 x 24.5 x 24 inch shell built for the storage bays of large coaches, horse trailers with living quarters, and off-grid trailer builds where water autonomy is the whole point. Off pavement, water is range - and this tank is over a hundred gallons of range.
The shell arrives exactly as you spec it. As a dual-role B-series molding it can be plumbed potable or as a holding tank, and either way the fittings are installed per order: print the drawing below, mark fill, outlet, vent, and sender locations to match your chase, and Ronco spin-welds or thread-installs each one to the mark. The on-page fitting planner keeps the sizes straight.
Take the loading seriously. The blank is 120 lb, but 110 gallons of water is about 917 lb - a load that belongs on frame crossmembers, with the tank full or near empty in transit rather than slosh-heavy in between. Molded in Tustin, California, where Ronco has rotomolded since 1974. Check delivery on a shell this size with the freight cost estimator, and see smaller steps in the RV water tank category.
