About a month ago, I finished installing the three roof vents. It was a little more of a job than I had anticipated, the originals were well glued in. I opted with two vents with metal covers and a Fantastic fan, metal cover, over the rear bathroom. All work great . I have left the inside trim loose with plans to purchase some type of overhead lighting. Vents were purchased from Vintage Trailer Supply and I was well pleased with their service.
Thanks to all who gave (and continue to give) this first time Airstream owner help from this wonderful website.
