Air Conditioner is not cooling the trailer

OP, remove the Air Conditioner grill that is screwed to the ceiling of your 5th Wheel. Once removed, you will see a divider that seperates the return air side of the AC unit from the supply air side. Make sure this hasn't fallen over to one side. This needs to be vertical, and it will seal the return from the supply. This has been a common issue found on these AC units. Mine had fallen over to about a 45* angle, and the supply was being pulled right back into the return, with very little airflow going out to the trailer. It made a big difference in the AC units performance making this fix.
