Assuming price is right, I'd buy from the dealer closest to you with the understanding that nearly ALL warranty work should be done in Jackson Center, Ohio.
Folks rave about Colonial, hate on Virginia, and know very little about Ansley.
The number one thing for me, no matter where I would purchase a new Airstream, is to take it to the factory for any significant warranty work.
