If you haven't seen it, Thor announced quarterly sales that ended Oct 31.
While the RV business, both sales and backlog, for all of Thor, is merely half of what it was this same quarter last year, their bus sales are actually up 13+%.
You can't put all of your eggs in one basket. Those that already own Airstreams are out having fun. As soon as the economy sees a break in the clouds, I'm sure we'll be adding to that ~60K number that is already out there...
