The Advanced RV owners have taken the B rallies to heart because many attend the Advanced Fest two weeks before and the owner of Advanced RV has been an attendee for a few years now for personal RV reasons and not to promote his company. It just became a natural fit.
Lacking are Roadtrek owners. They seem to have their many own gatherings around the country promoted by Mike Wendland. I attend his January Winter Freezeout in Michigan's Upper Peninsula. It gets over 30 RVers and proves you can survive cold and snow in a Class B.
