Camelot 40 paq 2005 had same moisture problem and have found and solved the problem. Depending on the rain direction which slide it might be.
Put any slide out, you will find they will all have the same problem, but some might not show up because the seal is glued over the hole. On a ladder go to the outside corner wall of the slide, just under the slide topper at the outside corner of the slide carefully pull the rubber seal away from the corner. What I found is the weld that goes all the way across the inside of the outside wall ends about 1 inch short from each corner of all my slides. Seal those corners with a good calk and put the rubber seal back.
The way I proved it was to pour some kids bubble stuff down the hole and put a low pressure air hose on it after about 5 minutes bubbles were blowing around the windows. All slides were welded short at the corners, so I calked all corners.
I just read this, and I know it sounds confusing, if you have questions feel free to ask rvdebree@gmail.com
