Dometic AC Leaking From Ceiling

We had a very windy, rainy period in Palm City Florida and a few days later I found water dripping out of a light fixture near the bedroom Dometic AC unit in our 2013 Georgetown. I checked the roof and all seams looked sound. Then later we camped in St Augustine for a couple of very humid nights (no rain). During the night water started trickling from the bedroom AC on to the bed so we covered the bed with plastic and put a pan to catch it. We moved to the living room fold-out bed and I turned off the rear AC and left the front unit running. But the water continued to trickle from the rear unit all night; almost a gallon.

When I got home, I removed the AC's cover and condenser panel and saw no debris blocking the white plastic condensation catch pan. So I took it to the dealer and they said the AC needed servicing and cleaning. They say the fixed it and ran it for a day and said it did not leak anymore. My question is, if the catch pan was clear, where does blowing rain and/or condensation build up in the AC such that it leaks into the bedroom?

Did you check the seal or the bolts to make sure they are tight.

There is a torque setting on the mounting bolts!
DO NOT just tighten them

Turbs is right, and along with a torque requirement there's a proper tightening sequence that should be followed.

Yes. Snugged them up good but it was still leaking water around the edges of the AC.

Maybe the seal is bad
