Here is an article about RV'ing and CCD Airstreams in today's Star Tribune.
Sorry about the headline, our headline writers are sickos.
Sorry about the login required, it wasn't required when I copied the link, but now it is. And for some weird reason, I can't delete this thread.
At any rate, the article states that the CCD makes up 40% of total airstream sales, which reached $1.4 B last year. That's an increase of 83% in two years.
