Six gallons of fresh water covers a weekend of drinking and dishwashing for two, which is exactly the mission of the Ronco RVB277. Catalogued as a 6 gallon light-duty polyethylene RV fresh water tank, it ships at about 10 pounds and fits the smallest water systems on wheels: teardrop trailers, truck campers, and minimalist van builds.
The RVB277 is rotationally molded from natural FDA-compliant polyethylene, forming one seamless shell with no joints in the wall. Ronco molds the resin without pigment, so the tank stays translucent and the remaining water shows through the wall itself, a practical gauge on a tank small enough to empty in a day.
It comes from the same Tustin, California plant where Ronco Plastics has rotomolded tanks since 1974, and it gets the same order treatment as Ronco's largest vessels: spin-weld or threaded fittings installed at the locations your specification requires, standard on every tank. Where a drawing is shown it depicts the blank molding. OneSource Plastics carries the RVB277 as an authorized Ronco Plastics dealer.
