Thanks to all for the replies so far.
Keith_h - I will look for the deflector the next time I pull the covers off but this is a new trailer and the fridge worked okay before with no changes made to the back of the fridge so if there was a deflector from the factory it is still there.
Dave - Yes, propane was the first thing I tried when it was not getting cold enough since propane is supposed to be more effiicient than electric. It still did not get cold enough suggesting low refrigerant or a faulty burner (?).
Vince - The door gasket is tight. Veggies are in the bins at the bottom but there was also a few veggies (green beans) on the shelves. These were removed last night but this morning the inside of the cabinet was still very humid as evidenced by the water on the fins.
Right now it is 94 outside and the fridge is now at 50 and 10 (fridge and freezer) but there is no direct sun on the side of the slide where the fridge is ... yet.
Kaadk - thanks for the tip on the control board.
Here are some pictures:
Freezer - notice the frost but yet the some of the freezies were not frozen. The ice was frozen though.
