AC leak question

[Civil_War_Buff]

Hey everyone,

This past weend, I had a couple of occasions to actually use my air conditioner (we had a small heat wave pass through California), and when I turned it off, it started dripping water from the seam where the filter panel attaches toward the front of the trailer. This happened once before when it was new and the dealer fixed it, but this time I am on my own.
Before I climb up on the roof and start tearing things off, has anyone else had this? Does anyone know where it might be coming form (other than the obvious :P )?
I am assuming that vibration may have loosened the hold down bolts thus breaking the seal between the unit and the roof allowing condensation water to take the path of least resistance and into the trailer.

Anybody?

Thanks,

Larry
