Leak in Front Closet

[thanket]

I have a 333mks Cougar fifth wheel. Their seems to be a leak in the front closet in the left bottom corner. I have had friends look at the camper and we re-caulked the roof in the upper left corner above where the leak appeared to be. Everytime we go back to the camper the corner in the closet is still wet. I called a local rv place and they sent techs out to look at the camper. They resealed a couple places on the roof including the place that I had already done. They said it is a very common place for the camper to leak. When I told him the problem on the phone he was able to tell me what kind of camper I had. The problem seems to still be there. We went to the camper last night and the hole in the closet was again wet. Any ideas would be greatly appreciated. Also, how long do I let the problem persist before I start worrying about mold and other problems?

Some photos of the exact location of the wet spot, the roof and the front of your trailer would help us understand what's potentially leaking, and give us a better understanding of what has been sealed/resealed. Just imagining "a corner" without knowing if it's the closet front or rear corner, left or right, and "seams on the roof have been resealed" without knowing if that's the side drip edge molding or the front cap molding, etc... Right now, the only "sure thing" is that there's water in the closet and "some parts of the roof have been resealed"... Lots more information is needed to "drill down to the exact recommendation".....

You might want to check the caulking around the running lights. We had a camper where they weren’t sealed correctly and leaked into the closet.

^ yes this was my problem. Our rig was a '13 Cougar 24 RKSWE TT so not the same unit but leak was at the clearance light.

I have attached 2 pics of the location in the closet. The carpet does not get wet just the hole where the white paper towel is.

I am not at the trailer to get a picture of the outside. My wife took pics of the inside and I posted them.

The concern over this should have started when it was discovered. Water is the mortal enemy of any livable space. Keep it as dry as possible and run a fan or dehumidifier to keep it as dry as possible until the source can be found. 2 questions, where does the "hole" go and does it leak when it rains? When stationary, or only after being towed?

I believe the leak is only after it rains. Haven't resealed around the running lights. That might be the next step. Also where the leak is that panel is going to come out this weekend so I can see what is behind their.
