I got some bad news today.
My Airstream has been located, and she has been destroyed. He sold the aluminum to a scrap dealer near Midland/Lubbock in East Texas on the Friday after it was taken. He waited while they removed and weighed the Aluminum, took the money and left. He told them he would be back for the frame later, but never returned.
I'm really disappointed and a little heartbroken, so I have asked that this thread be closed, so I can move on and focus on things I can actually do something about.
I would like to thank everyone for their supportive comments, and for keeping an eye open, just in case we got lucky.
