Yup, Darl, this trailer has been exhaustively discussed from its inception as only an active forum with a passion for small fiberglass trailers can!
These are the two longest and most complete discussions.
This one is a general discussion/critique of the design:
Introducing Nest Caravans
This one chronicles the building of the prototype:
Building the New Nest Caravan
Both end with some discussion of the Airstream acquisition.
The Airstream forum has its own conversations going with a different slant, as you might expect. If the end result satisfies both groups, it will be nothing short of a miracle!
Looks like a long wait (late 2017, I believe) to find out.
