Horse trailers with living quarters, hunting rigs parked a long way from a spigot, mobile detail and grooming trucks: the common thread is a working vehicle that needs a big, dependable supply of clean water on board. The RVB387 answers with 92 gallons in a light-duty Ronco B-series molding - enough fresh capacity to run animals, equipment, and people through a full day or a long weekend without hunting for a fill.
The molding weighs 133 pounds and is translucent natural polyethylene, FDA compliant for potable use. That combination reads simple but does two jobs at once: safe drinking water, and a visible water line through the tank wall so you always know where you stand. Ronco has molded potable tanks in Tustin, California since 1974; this part comes off that same proven tooling.
Ronco installs fittings to order rather than molding in a fixed layout - spin-welded or threaded ports, placed at your marks. Before ordering, print the technical drawing below, sketch where your fill, vent, and outlets need to land for your plumbing runs, and confirm it in the fitting planner on this page. Loaded weight deserves the same forethought: at 8.34 pounds per gallon, a full tank rides best low and over structure.
