Well I finally received what I was seeking - and figured others might like to have this information too!
A huge THANK YOU goes out to Vicki at Airstream.
While some have commented that seeing / experiencing the trailer first hand is a good idea - the fact is for some AS Hopefuls - this may not be so easy (and may be impossible others).
As such - having measurements may be helpful!
What follows is a cut&paste of my correspondence form Vicki...
Thank you for your continued interest in Airstream. Following are some measurements received from our Engineering Department:
I have listed below some general dimensions for the three floor plans of interest. Most cases these are rounded off, squared off for a reference only, as nothing beats a trip to the dealer to walk through and experience the feel and space. I certainly would suggest experiencing the space for each model.
