Hi Jim, welcome to the forum. We've owned our 2006 for almost a year and we love it. I think everything that moves requires some kind of maintenance. What impressed me most is how much better the Airstream is built than other brands. It has a belly pan that encloses all the plumbing and holding tanks. It sits lower to the ground, giving is a lower center of gravity and more stable on the road. The classic styling is always a good conversation starter when you come into the camp.
Like CWF says, contact one of the volunteer trailer inspectors here on the forum. There are a lot of friendly folk here with plenty of experience and free information.
Good luck in your search
