Airstream to Scotland
Bobby - Getting an Airstream to Scotland should not be a real problem. Cost a bundle, even for a canny Scotsman, but definately do-able. One problem you may not have considered is its size. Depending on your choice of Airstream, it may be too large (width & length) for the legal limits of what can be used on your roads. Another concern may be how you plan to tow the trailer. The generally smaller and lighter, vintage model Airstreams could be towed by a Discovery, but there is all sorts of discussion on this aspect that you should look into before you import your Airstream.
By the way, this is a great Forum for you to brouse and discover just about all you will need or want to know with reference to buying, repairing, using & loving an Airstream.
"Aluminitus" (defined as an almost incurable desire to own/restore/enjoy at least one Airstream trailer) is contageous. Welcome to our world.
