We are looking at bikes this weekend but I need to think about the Airstream bike rack.
When I look at the back of my 2008 Airstream Class 25 the vertical rivet lines from the bumper up to the rear window are intercepted by the inboard edge of the tail light assemblies. Looking at the photo at the Airstream site showing the bike rack mounted on the back of a Classic shows the light assembly on that Airstream is just outboard of the rivet line and the bike rack brackets are mounted inboard of the tail lights. With my Airstream's tail light housings covering the rivet line mounting the brackets would be on bare aluminum with not framing to support the bracket.
Those of you who have installed the Airstream Fiamma bike rack on your Classic model, can you post some photos of your bike rack so I can see how the brackets are installed?
The photo shows the rear of my 2008 Classic. My taillights are mounted higher than the Classic shown this photo on this link
I'm thinking I would have to lower the brackets a few inches to where they would be secured just underneath the tail light housings so I can hit the frame.
