condensation or leak?

[Tom_Barb]

about 2 years ago I replaced the old entertainment center and TVs in our couch, In doing so I noticed the insulation over forward portion of the coach was wet. Thinking leak, I removed the wet stuff, Then I sealed all the seams with Eternabond tape as per instructions for use.
ran all new HDMI cables, then replaced the insulation.

all was well until I was required to replace the HDMI cable, I noticed the same wet insulation.

the Question is how do I determine if it is condensation reoccurring ?

I have checked for leaks during the heavy rain this passed week. shows nothing on any seam I can see where the wet insulation is.

the cabin roof where this is occurring is simply 1 layer of fiberglass with 1 seam across the roof, which is sealed with tape.

Check the bolts holding your air conditioner -- That`s often the cause of leaks toward the front, & elsewhere - Bill Willard

Maybe as stated lights and is your antenna and if you have that mini battery charge in that area. Maybe wind driven when you are driven. I got it on my 99 same thing. Could really never find it but removed the light and seal them along with the antenna and charger line. It did go away, but as stated never did find a leak. Every looked good when taken apart.

If you have clearance lights in that area you may want to check them. The silicone that is usually used is not very good. I redid all of mine with Dicor and eternabond.

the wet is about 4 feet back and up hill from the lights.

after being open all night it is dry.

never has been wet enough to leave a stain on the ceiling
