Don't know if what I have to offer will help with all the good advice posted so far but here goes.
Took delivery of 2015 Classic from Bay Area Airstream in Fairfield, CA in April 2015. Dealer did a great job of PDI and Blue Ox hitch setup. Had it delivered by 3rd party to Las Vegas to avoid CA sales tax (SC tax $300.00) Was on an extended visit in San Diego at the time. Since then, have traveled back to SC, NC several times, MD several times and once to Jackson Center. Just arrived back from a 8,000 + mile trip out West through the Dakota's, MT, CA coast and Napa, Denver and home. So now more than 20,000 miles. Here are my minor travails.
Almost all failures that had to be corrected at Jackson Center were non-Airstream components. A/C thermostat sensors, 3rd jack replacement and minor adjustments. My list was about 15 items long but so inconsequential that I don't even remember them now. What I do remember is the absolutely GREAT service I received at the factory. As a RV'er for more that 13 years and owner of 5th wheels and Class A's and suffering from shoddy service from independent dealers and Camping World, I would never go anywhere else but the AS factory.
In fact I am scheduled back for another service (under warranty) in October. The new list is again 16 + items with all being minor AS issues or outside vendor equipment problems. Such as:
Rear bedroom floor squeaking.
5-6 ceiling rivets popping out.
Front curved window shade tension broken.
ZipDee Awning issue on opening
Steps not locking in down position
Power jack failure to hold in extreme position. Will request Atwood replacement
Leak at hot water heater (minor)
12 v fuse diagram
Pantry and drawer locking issues
Again these are minor and maybe a dealer can fix but I trust AS factory and not the dealers. And a little side trip to OH never hurt anyone.
