This is an Airstream built for the European market with axles positioned for reasonable noseweight, overun brakes & a 50mm hitch. A US spec Airstream has electric brakes, I think & axles set further back with a 2" hitch.
Id like to have a good look around one, but dont think that I would purchase one if it were half the price. If I had that kind of money, Id probably think about a Campervan and a small car to be towed, and then talk myelf out of it as C'vans are more practical. Lovely thing, but to much money for what it is.
