Greetings from the Florida Panhandle
First off, welcome the Forums. We're glad to have you with us.
The 22 Sport sounds like a decent deal. It is a brand new Airstream, even though it's an '07. The Factory Warranty starts on the day that you take delivery. We bought our Lucy brand new in June of 2006, and she is a 2005.
The 22 Sport is light and towable with a greater variety of tow vehicles. If the floor plan will work for you, it sounds like a deal to me.
