The RV45W is a 35-gallon fresh water tank molded in natural, FDA-compliant polyethylene - the translucent light-duty resin Ronco reserves for potable service. That translucency is a working feature, not a cosmetic one: you can see the water level through the wall with a flashlight, which matters when the sender fails halfway through a two-week trip.
Ronco's maker sheet lists this shell as the 45W at 35 gallons, and its dimensions live on the technical drawing below - print it, tape it into your bay if you like, and confirm clearance before ordering. If the outline does not suit, three other 35-gallon fresh shapes exist: the RV34W at 33.5 x 19 x 16 inches, the RV1W at 19.5 inches wide and 15 inches tall, and the RV2W at 37.5 x 19 x 12 inches. The rest of the family is at RV water tanks.
Plan mounting for the full load, not the empty one: at 8.34 lb per gallon, 35 gallons is roughly 292 lb of water riding on your floor structure, while the empty shell weighs just 18 lb.
