I'm relatively new myself, having just bought my Airstream Interstate about three months ago.
I'm one of those people Doug & Maggie were talking about. Can't hook up for camping or rallies in the immediate future, though, thanks to some emergency (but fortunately minor) foot surgery earlier this week. The timing of the surgery was good, though, because my Airstream is in the shop for a warranty repair anyway. The surgery doesn't take away camping time that I hadn't already lost. I'll just have to make up for lost time when I get both my Airstream and my foot back.
