Ronco Plastics offers several distinct 5 gallon RV fresh water moldings, and the RVB390 is the one to choose when its particular shape matches your cabinet or compartment. It is a light-duty potable tank shipping at about 10 pounds, at home in teardrop trailers, slide-in campers, overland rigs, and compact van builds.
The construction story is the same one Ronco has told from Tustin, California since 1974: rotational molding produces the entire tank as one seamless polyethylene piece. The resin is natural and FDA compliant for drinking water, and because it carries no pigment, the translucent wall lets you see exactly how much water remains.
Even at 5 gallons, the RVB390 ships with fittings installed to your plan. Ronco locates spin-weld or threaded fittings per the customer's specification on every tank it sells, so the fill, vent, and outlet suit your plumbing runs from day one. Drawings, when shown, depict the blank molding before fittings are installed. OneSource Plastics carries the RVB390 as an authorized Ronco Plastics dealer.
