First time running the a/c for me (NW Florida), and it works great...the condensation just runs off the roof, right? I wouldn't think there'd be a collection pan and a run-off hose...just checking...
There is actually a "pan" inside the AC unit that drains to the outside of the roof that can get clogged after significant user that promotes algae growth.
I have a similar drain channel as jeff that is made out of a black rubberized material as a J channel.
you can also tilt the trailer front/back and side to side a bit to help control where the runoff happens without disturbing the levelness that much
