Another Water Intrusion...

We found the second water leak and it brought some other surprises.
The passenger side mirror wasn't sealed along the top of the mirror mount. This allowed water to enter at the top and run down directly to the front top screw. This allowed the water to enter into the coach wall and soak the wall boards.
Here is some of the damage that caused:


The other thing we found was the outside mirror had almost nothing that it was screwed into.  Look closely at this photo and you can see the screws coming through the Styrofoam.(One is just above the electrical wire and the other is near the top right corner.
-And I shouldn't forget to mention that the only thing besides the fiberglass wall and the Styrofoam that was holding the mirror was this thin layer of rotted out OSB.
