I noticed some water in the shower after a rain. At first I assumed it was from some pin holes on the roof. That will be another project.
Upon further inspection, I think the water was coming from a leak in the rear window. My old friend google informed me that RV windows should be resealed every so often. I also learned Butyl Tape seemed to be the best product to use as a replacement sealant. So I measured all the windows and ordered what I needed from Amazon.
A couple of helpful videos for resealing the windows:
So here are some images of the water and leak:
I ended up resealing all 5 windows. I need to let the sealant settle in and the go and trim the excess butyl sealant. I also replaced all the screws with new stainless steel screws. It was a lot of work to clean the old sealant off the frames and fiberglass siding. A scraper, elbow grease and acetone did the job.
I will update this post with some photos once I trim and clean the excess sealant.
