I was there yesterday (Thursday). Pretty much the same cast of characters as previous years - although Tom Raper is now a Camping World dealership. It's always fun to attend and "kick the tires". With the weather coming in this weekend, it's also nice to dream about being some place warmer with the trailer.
I didn't notice any new RV dealers there - looked like maybe Camping World expanded their display area from what Raper had last year. If you go to the Dayton RV show web site, there's an exhibitor floor plan.
