After returning from 2 back-to-back trips, we saw nothing but relatively full RV sales lots. If there's a shortage, they're hiding it well.
I feel as though Thor's math might be a bit fussy. Perhaps someone should ask them, of this tremendous backlog of orders, how many are actual sold units (retail, with deposits in place) and how many are dealer inventory orders? BIG difference as I see it, but it creates the illusion for the potential buyer, especially the newbie, that if a unit is available, anywhere at any price, you'd better jump on it, or risk having to wait 'til the cows come home to buy one. Great (although somewhat deceptive) marketing.
