Where you put 92 gallons of water matters as much as carrying it. Full, the RVB483's contents outweigh the 118 pound tank several times over - water is 8.34 pounds per gallon - and that mass moves with the vehicle: it loads the axles, shifts the handling, and works the mounting floor every mile. The builds that get big fresh tanks right treat placement as a chassis decision first: low, centered over structure, near the axle line. This B-series molding gives you the capacity; the drawing below gives you the footprint to engineer around.
The tank is Ronco's light-duty potable spec - translucent natural polyethylene, FDA compliant for drinking water - molded in Tustin, California, where the company has run its B-series tooling since 1974. Light-duty is the correct wall for a tank that sits on a supported bay floor; the translucent wall doubles as a no-hardware level gauge.
Ronco installs fittings per order, spin-welded or threaded at your marks, which pairs neatly with the placement work: once you know where the tank rides, you know where the lines run, and the ports can be put exactly on those runs. Print the technical drawing below, mark it up, and lock the layout with the fitting planner on this page.
