When the water seeped in, the path it followed was to go around the glass, which is in a channel, and then down the wall. It wet the arm of the gaucho, which was moldy afterwards. There was a water stain on the wood subfloor in that corner (the PO had replaced the carpet with Perego snap-in flooring in the front half of the AS).
The AS tech pointed out to me that the window sealant had been cracked and a part of it had actually fallen off. Because all this was behind the dark plastic rock guard, I would not have found it unless I unscrewed the fastening holding the guard in place (the guard is hinged so it can be swung aside). The repair was itself was not complicated, as it just meant removing the old hardened and cracked caulking around the window and replacing it with new sealant. The change of the gasket was done as a preventative measure (it was 25 years old).
As a result of that service I had done at JC, I have made it a point to visit there twice yearly (on my fall trip south for the winter and again on my return north) to regularly do my servicing there. Besides the competence, I like the fact that I get a fixed appointment and whatever work has to be done is done without having to leave my AS there. If the work takes more than 1 day (and it has on occasion) they have camping facilities there - they pull the trailer onto the terraport and I sleep in it overnight; then it's back in the shop at 7:30am. On my first visit there in 2011, when they repaired the leak at the bottom of that window, they also found water seeping in around the rivets where the front end cap is attached. I opted for a permanent repair, which meant that they drilled out and hand bucked in new rivets. That and other upgrades had me camped there for 10 days - and you don't want to know what that cost.
