Had kinda the same problem but the water ran to the back of the camper and on to our clothesdrying on the close hanger thingy on the ladder, wife was frustrated that the bathing suits and towels would never dry in 90 degree heat at the beach. I just laughed and proceed to fix the problem. I just went to Lowes and bought door air seal in 15 ft. lengths and diverted the A/C water to the other side of the camper. Just clean the roof where you want it to go and just stick it down to the direction you want the water to go run. So far it`s held up to the rigors of highway speeds but if it ever comes off just put down some more, easy and cheap. The wife thinks I moved the sun and the stars and still haven't figured out how I fixed that. I give up on posting pictures it`s so much easier on the other forums.
