Along the lines of the other's who have found issues with the sealing of their AC's... I was cleaning the filter when I found a piece of foam laying in the AC. Turns out it was the divider between the cold output and the return.. Fixed it up with some Gorilla Tape and, well, now the trailer is cooling MUCH better. It was not BAD before but it is amazing when the cold air goes into the trailer and not sucked back into the AC.
