I've only had the chance to examine one Airstream (at St Palais-sur-Mer last year) and I wasn't all that impressed.
As a fashion statement of the 'look what I've got' type it was quite effective as a lot of people were stopping to comment, me included, but on close examination the finish was crude with all those exposed rivet heads and great wodges of sealant oozing out of all the joints.
The interior was, to my eyes anyway, tacky, all black and white leather, chrome and shiny surfaces. The Yorkshire expression is 'like a whore's garret'.
Eribas seem to me to be much better made, less ostentatious and altogether classier, particularly those made in 2003.
