I went to check on my trailer a few weeks ago to see how it was doing and I found water and wetness on the seat cushions and table. Not much my things were damp. I decided to dry things up and place a 2" deep plastic tray under the center of the rear window on the table. I knew that a rather big storm was coming our way and we were supposed to get between 2-3 inches of rain from this storm. The next day after the storm, I went to the trailer to find this plastic tray almost filled to the top with rainwater coming in somewhere along the top of the rear window. I could see droplets of water hanging on the inside window frame. I thought that this problem was fixed by the dealer, but obviously, it was not. I did notice that the sealant that was used is drying out and falling apart. I temporarily applied some new silicon sealant around the top window seal outside to see if this might stop the leak until I can do a better job of fixing this problem. I also noticed the sealant almost gone on the small window next to the entry door. I too applied new silicon sealant to this frame and hope that I fixed any problems with that window leaking.
My brother-in-law also suggested that I bring the trailer home, hook it up to AC, close the trailer up tightly, turn on the Air Conditioner and check for leaks around the windows with a soapy solution. Any bubbles on the outside would indicate where the air leaks are and most like where water is entering the trailer through the window frames. Good idea. I will have to try that, possibly in the spring.
