I finally solved the window leak in my Airstream 22FB. As instructed by the Airstream mothership, I used 100% silicone around the windows. Thus far, it is working great! Thank you Airstream Help Desk! I have a new leak around the skylight that needs to be addressed. I do have one small complaint about the Airstream factory when they are putting these travel trailers together on the assembly line. Thanks for watching.
