OK, problem is solved but we don't know how or why. LOL. A friend here at the campground came over with a voltmeter and measured every fuse. They all checked out fine, even those that I wasn't aware of in the outside portion of the fridge. He put everything back together - and it worked! Something must have wiggled loose during the drive, although I wish I knew which one! The entire fridge was getting now power - no light inside, controls on the door were out, everything. Anyway, all is working now.
