Starting in either 1957 or 1958, Airstream offered an extra large unpowered roof vent called an "Astradome." It was the standard 14" wide, but 25" long. It's a neat 50s Airstream feature that I decided to add to my trailer.

The hardware is all the same as a standard 14" square opening, so all I needed to do was stretch the opening and mount a reproduction lid. The only thing left undone is to make a long screen for it.

Now my living room area will have a large opening in the ceiling and my galley and rear bedroom will have powered fans.
