More information and thanks for all the comments. We are home and the fifth is sitting headed north but the scrubs on the drivers side are higher than the fifh so shade on that side until the sun changes to expose the back and soon the shade from the tall scrubs has that side in the shade, Fridge in the slide and has cooling fans that scream but didn't seem to hear them during the time the fridge was warm and no food in the fridge but frozen food in the freezer. Freezer is 10 degrees and the fridge is 40 at this time of 7:pm Thermistor is not attached to a fin and doesn't show as what we have had in the past rv's. Trailer is sitting level. the 30 amp power has gone out before the issue but have a 20 amp heavy cord powering the trailer and just the fridge is running on that. I feel it might be ok but we will head south again this September. chevman
