Welcome!
I am sure you will enjoy your new beautiful Airstream! I might suggest that once you take delivery of your Airstream you stay close to the dealer for several days as you go through the trailer and see how everything works for you. Make copious notes. Anything that needs fixing/tweeking/repair should be covered by your warranty.
Also be sure they walk you through how to operate
all the systems, try it yourself and don't leave until you are comfortable with how it all works!
Be sure and join in on some rallys. The very best thing about owning an Airstream is the fine people you will meet. Look at the rally calendar at the top of the forum page and drop in as you travel across country! Naturally, be prepared to give tours of your new lovely Airstream!
