Are RVs delivered winterized in cold environments?

I do not understand why ANY dealer would winterize a motor home. To the best of my experience they are delivered dry . . . there is nothing to winterize. Air doesn't freeze!

I believe the manufacturers test their water systems at the factory before delivery so they are not manufactured dry. They must be winterized before leaving the factory. In fact, the manufacturer put a sticker on the window stating that they had winterized the coach.
