Eighty-three gallons buys silence: no generator run to a fill station, no campground reservation made just for the spigot. The RV70W is Ronco Plastics' big-but-not-biggest fresh tank, an 86 lb light-duty molding for rigs that treat dry camping as the default rather than the exception. Its shape is documented on the drawing below.
The load math: about 692 lb when full, which belongs in the same planning conversation as your axle ratings and hitch weight. What you get for carrying it is Ronco's proven potable construction - FDA-compliant natural polyethylene, translucent wall that doubles as a level gauge, one seamless rotomolded piece.
Above and below in the range sit the 90-gallon RV64W at 39.25 x 39.25 x 14.5 inches, the 76-gallon RV65W, and the 75-gallon RV61W. See RV water tanks for everything else and the freight cost estimator for shipping.

This tank has a molded shape (see the drawing), so it is sold as a blank tank with no fittings installed. Add the Ronco 3-inch uniseal (F3UNISEAL), a loose pipe-to-tank seal you install yourself, if you need a sealed pipe connection.
