I would try to find a buyer (not on ODT) who was looking for a Airstream. I figured someone has to have fixed these up -- and they have but it is not cheap. Here is the link to a top end reno that was $54,000 including the trailer and ripping the insides out. I am sure there are people looking to do the same.
