Don't be discouraged !
We bought our 27 Flying Cloud in February 2011. I agree with whoever said "use it right away." There is absolutely no better way to identify and shake out the "kinks" than to use it. In the year we've had ours--17 times out--I have found numerous minor problems, a door lock that didn't work right, a water heater that wouldn't start, ceiling lights that stopped working, a leaking water tank, etc, etc. The majority were irritants and easily fixed, sometimes with help from members of this forum and twice by the dealer.
You cannot judge the reliability of a TT by the same standards you would a new auto; besides, if Airstreams were as reliable as similarly priced cars, what would we do with all that spare time ....
I've found this Forum to be a huge benefit; there are so many experienced, willing AS owners who share common knowledge and experience. It helps that there are always some who have the same, or very similar model as yours.
So, once you get through the "shakedown" period you'll be able to move on to the "improvement" period and join in on endless conversations about batteries, lights, tow vehicles, hitches, and all manner of gadgets and upgrades ...
It's a hoot; welcome.
As far as I know, this is the oldest I've ever been.
