Water Damage below window Drivers side

[mhbell]

A couple of weeks ago after another rain storm I noticed that the sidwall below the drivers window appeared to be distorted and starting to bulge. Today as I investigated It was much worse and I found the the plywood under the wallpaper was delaminating and coming apart. I peeled of the wallpaper around the area that was bulging and found that the plywood was wet. There is no sign of water damage on the ceiling or anywhere else. I used a moisture detector and this is the only are with moisture up to 24 % These windows are called frameless windows. SWo far I've been unable to determine where the water water leak is. has anyone else with a vegas or axis had this problem? Any help appreciated. see pictures below.

If the windows need resealed, you'll need butyl sealant strips (comes as a roll) and then non-sag lap sealant, I am currently resealing my roof but the windows some next. Its a bit of a process but pretty straightforward, lots of screws to remove, breaking the butyl stickiness to the side, and maybe a helper on the inside to help ease the window out, scraping and cleaning, then reinstall

I have been told (and believe part of my own problem is) the cap moulding that runs along the seams, I found several broken rivets and the roof had separated away from the side, plus the where the front cap and side attached had started to come loose. I drilled out the old rivets and used some longer aluminum rivets and butyl caulking to reseal underneath and inside the holes, then non-sag lap sealant to seal the top of the moulding as well (you can see this in my roof reseal topic) https://www.irv2.com/forums/f115/res...es-611719.html

MY coach is not the same model as yours, but I am betting the build procedures are pretty close
