If it's a standard production unit being built off the main line, the answer would be no way. How do I know? Back last October I asked the factory directly a similar window question when I ordered our Safari and was told if I wanted any of the Classic windows, I need to buy a CCD or Classic.
BTW, I believe the CCD and Classic front wrap around windows are the same.
Airstream does have a custom coach building sort of department. The do build custom coached taylored to individual needs/wants. However, expect to pay a beyond premium price on top of the cost of the standard coach off the line.
One side note is that the windows on the current Safaris are not all that great. One thing that I can't understand is the window thing on the Airstream lines. What I'm getting at is that Airstream has a reputation and all the coaches cost a pretty penny. None of these units new are inexp. I can understand and fully support and accept the fact that if you want the real wood interiors, you need a Classic. If you want the Euro look, you need a CCD. However, one of my main gripes is the window situations. I feel that the Classic/CCD window design is a vintage looking thing. The shells on a Classic and CCD are identical. Why not lessen the internal rib work and make an Airstream and Airstream and stop putting the cheapo windows on by making the retro windows across the board? Vista views could still be an option, but the core window IMHO should be the same. I mean Airstream is bringing back lots of the vintage stuff, why not make life easier for thier customers and their line workers. Standard Airstream retro "Classic" windows across the board.
