This has happened to us as well especially when running the air conditoner all night long in a high humidity time period. What we usualy find is checking the roof mounted 14" x 14" roof mounted gasket we will notice it is not tight. This gasket should be depressed at least a 1/4-inch. You can observe this gasket by just pulling down the inside panel where you air conditioner filter is located.
Here is pictorial side view of an installed roof air conditioner showing the location of the ROOF GASKET
This is what the gasket looks like
Looking up inside the bottom side of the roof installed air conditoner you will see four LONG screws that holds the bottom section to the top roof air conditioner section. These may tightened to show at least 1/8-inch to 1/4-inch depression of the square air conditioner gasket.
Note these four long screws are the only thing holding your roof mounted air conditioner to the roof of your trailer. Interesting concept haha... Rough Road Vibrations and probably aging of the large gasket requires it to be re-tightned at times.
I used to run the I59 road in northern ALA on several trips to TEXAS and BACK and they had concrete road sections bulked there for 50-60 miles. My poor trailer would come off the ground going through there at almost any speed I would go. All the nig tractor trailer truck would be running down the side of the road there where it was smoother haha... I had to re-tighten my four air conditioner hold down screws alot...
just my thoughts
