Is this a bad circuit board? (fridge)
Its the type that uses the resistance probe. Which is all fine and dandy. I have not measured the ohms but assume its measuring accurately. Lets pretend the temp probe was hanging off the fins. Re...

Over thinking things.
Dump the 24/7/365 monitoring and don't obsess.
Your A/C and inside trailer temps has zero to do with the fridge temps.
RV fridges are exposed to the outdoor temps and seeing short 45F spikes on overly hot days is pretty much the normal range of a RV fridge. While 45F is sort of above my comfort zone for refrigerated foods it isn't going to kill you, it just means your foods will not last as long as possible.
You mention "overly hot" which I take as the daily outdoor temps and what you see for the fridge is a direct result of the outdoor temps.
Some RV manufacturers will include a couple of small fans on the back of the fridge to help with the high outdoor temps, perhaps you might wish to look into that but I doubt your going to see a big improvement.
Camping off level also does affect RV fridge efficiency, RV fridges use gravity to move the coolant inside the tubes, off level operation slows the coolant circulation (yes, I know, there are folks who claim the fridges were redesigned to work off level, but reality is off level operation should be avoided for best efficiency).
Consider yourself lucky, one of the RV fridges I dealt with would peak at 55F for several hrs with outdoor temps over 95F and then would freeze everything solid in the fridge when night time temps dropped to 70F.
