Hi there DW :-)
I'm guessing when we pulled in and shut off the battery before connecting to shore power, something funky happened to the circuit. We turned on the fridge last night before taking off this morning and I know it was running in propane because I heard it fire up last night. the only other thing I can think of is something got off kilter when I ran over that tree stump. Of course, the fact that it's still reading 60 after being on for 20 hours is bumming me out but we'll keep a close watch on it.
By the way - for those if you playing along, I got pretty much every user manual in that briefcase you get with the new unit except for the fridge so I found a PDF I thought was close enough on line. I'm not exactly sure what model fridge I have! :-)
