There is one major feature that makes an Airstream Iconic to me, and that is the Door-Within-A-Door! I have had several RVs over the years, and the downfall for each of them was the separate screen door, as it never quite fit properly, always in some way interfered with the operation of the main entrance door, and made accessing the main door lock/handle unnecessarily complex. The Door-Within-A-Door is one of my absolute favorite features on my
1964 Overlander Land Yacht International -- I just wish that my 1978 Argosy Minuet 6.0 Metre also had one!!
