That gasket failure is not uncommon.
However, Airstream does not and will not sell that gasket to anyone, not even a dealer.
But, all is not lost.
Purchase some gray Sikoflex.
Clean the gasket, and the area that it touches, the edge of the metal frame and the glass next to the gasket.
Install a small bead of the Sikoflex to completely cover the gasket.
Where the gasket has pulled away, push it back in place, and hold it there with some small pieces of duct tape, leaving gaps between pieces of the tape.
Install some Sikoflex in those gaps. After a couple of days, remove the duct tape, and install some Sikoflex, in the bare areas, where the duct tape was located. That will complete the bead of sealer.
That process is much easier than taking the window frame apart, since getting it back into it's proper shape, is very tricky.
I notice that the inside latching brackets of your windows are getting rusty. That would suggest that the window gaskets are leaking, and if so, should be replaced. A "D" shaped gasket is now available that is far superior than the original window gasket.
