The RV58W flips the usual trade: a full 45 gallons of fresh water capacity in a shell that ships at just 25 lb - the lightest molding on Ronco's five-strong 45-gallon fresh bench, and a gift when the tank has to be walked through a camper door and threaded into a cabinet by one person. The maker sheet lists it as the 58W L.D.
Light shell, same physics: full, this tank holds roughly 375 lb of water at 8.34 lb per gallon, so the cabinet floor and straps carry the real load. Light-duty potable spec throughout - natural FDA-compliant polyethylene with a translucent wall that shows the water level at a glance.
Its bench mates cover the other priorities: the RV47W publishes its dimensions at 36 x 23 x 13 inches, the RV51W is the heavy-wall build, and the RV46W and RV5W carry their own outlines. Compare them all at RV water tanks. The RV58W's outline is on the drawing below - print it, check your cavity, and mark your fitting locations; fill, vent, outlet, and sender are spin-welded or threaded per order in Tustin, California, where Ronco has molded tanks since 1974.
