After lurking for about 4 years, trying to learn as much as I could before making this decision, I am finally purchasing an Airstream. Unfortunately, it will be about a month before I pick it up, but after waiting this long, another month isn't too bad.
We're getting a 2007 Classic, of the 34 foot variety. At least this way I won't be thinking about needing a larger one.
I do appreciate all the help that so many of you have unknowingly been to this lurker. I'll probably be actively asking questions soon, as this is my first rv of any type.
