Single-digit mold numbers are the old guard of Ronco's library, and the 5W is one of them - a 45-gallon fresh water shape that has been earning its tooling space in Tustin, California across five decades of coach builds since 1974. Molds this old survive on one merit: installers keep finding cavities they fit.
Listed as the 5W L.D., it is molded in the fresh line's natural FDA-compliant polyethylene with a translucent wall - watch your water level through the side instead of trusting a sender. The shell is a stout 78 lb, second-heaviest on the 45-gallon bench, and the load is the usual arithmetic: 45 gallons at 8.34 lb per gallon puts roughly 375 lb of water on your mounts.
Alternatives at the same capacity: the dimensioned RV47W at 36 x 23 x 13 inches, the light RV58W, the heavy-wall RV51W, and the RV46W. The full fresh line is at RV water tanks.
