The RVB272 is Ronco's beefier take on the 7 gallon RV fresh water tank, shipping at about 12 pounds with correspondingly thicker walls than its lighter stablemates. It is a light-duty potable tank for small RV water systems: teardrops, campers, overland trailers, and van builds that want a durable compact supply.
Natural FDA-compliant polyethylene is the entire recipe. Ronco molds it without pigment, so the translucent wall shows the water level directly, and the rotational molding process yields a one-piece seamless shell with no welds or joints to weep as the tank ages.
Every RVB272 is molded at Ronco Plastics in Tustin, California, a rotomolding house since 1974, and ships with spin-weld or threaded fittings installed to the customer's specification, standard on all Ronco tanks. That means your fill, vent, and outlet arrive placed for your build, not for a generic diagram. Where a drawing is shown it depicts the blank molding.
