A 150 gallon fresh tank is ranch equipment as much as RV equipment. The RVB494 gets built into livestock trailers, remote work camps, and washdown rigs precisely because it carries enough water to do jobs - watering animals, rinsing equipment, supplying a crew - rather than just supporting a vacation. It is a light-duty Ronco B-series molding, 132 pounds empty, and the technical drawing below defines the footprint you will be building around.
The material story is the same one Ronco has told from Tustin, California since 1974: translucent natural polyethylene, FDA compliant for potable water. For working use that combination earns its keep daily - the resin keeps the water safe to drink, and the see-through wall answers the only question that matters in the field, which is how much is left, without a gauge that can fail.
Do the weight math before the mounting: 150 gallons at 8.34 pounds per gallon is a substantial rolling load that wants to ride low and over structure, with the tank base fully supported. Then do the fitting plan: Ronco spin-welds or threads every port per order at your marked locations, so print the drawing, mark fill, vent, and outlets where your system needs them, and confirm the layout with the fitting planner on this page.
The RV water tank category covers the smaller sizes, the Ronco Plastics hub maps the full line, and the freight estimator turns shipping into a number. OneSource Plastics is an authorized Ronco Plastics dealer.
