Ashamed of his work.
Started main 15k dometic a/c unit at 6am and set it at 72 degrees.
Came home at 430 pm to find the camper 83 degrees.
Outside air temp was 85.
Shut main unit off and turned on the bedroom 13.5k and went to sons baseball game, I returned about 730 pm to find camper a cool 72 degrees.
So I decided to look into the main unit.
This is what I found.
No sealing tape whatsoever on the fresh to return air baffle, basically the cold air was returning right back to the return.
I spent 25 minutes getting the baffle back into place and sealed it up completely with aluminum tape !
Current temp in the camper is 68 degrees
