We decided on the 22' Sport
We couldn't get our dealer to budge on the price of his 2012 23FB. They had eight 2012s and were not allowed to drop below invoice (which he showed me). I do not believe any dealership actually pays what the invoice says but I could be wrong when it comes to Airstream.
So, the wife and I purchased the 12K less expensive 22 Sport and are very excited to use it. The dealer is installing the front segment protectors and 30lb tanks with aluminum cover. I'm currently working out of state until April 1st but as soon as I get back it is off to the woods.
