Think you will find that the Airstream come in to the UK fully fitted now -- it was the previous company at Tebay that used to fit them out here. The designer at Tebay now works for Airstream so there is continuity.

Thanks Ted, yes, you may well be correct, I re-read their details and it may just be the soft furnishings they fit out:

Courtesy of the Airstream-uk.co.uk web site:
“The Swift designers have brought a stylish twist to this all American icon with two distinctive furnishing schemes called Manhattan and Americana, both come with leather upholstery as standard with Impala fabric as an option. Easy to clean, Impala has a soft suede like feel and has been cleverly treated in manufacture to resist stains.”

I have asked them to clarify anyway...
