Sorry about posting my name as the message subject - perhaps the administrator can change that. The actual subject should have been "Closet Leak" (I guess). I have found some discussion threads that are similar to my problem, but have not found one where the moisture appears to be in the wiring conduit. I probably should also have said that it did not seem like a lot of water - but it made a shirt damp that was up against the harness.
The wiring harness is running parallel to the waste water vent PVC pipe. I looked at the roof but did not notice any obvious reason for the leak. My message is a bit panicked as I had significant water damage in my last RV and it seemed to take every bit of my free time to rebuild the unit (ended up taking wall board down and replacing the studs on the left and right front of the unit as well as the rear). Hope to prevent this recurrence if possible.
