This is heads up for all who are thinking of buying a new Airstream to be very careful. It is all the rage within the A/S community regrading units built in the last 10 years and includes new units as well. It appears the the clear coating applied by Alcoa is defective, and corrosion can be even be found on new units on the lot!! My 2004 28 Safari is full of the stuff. Thor is running from the problem and it is a damn shame. My suggestion, if you want the airstream experience. is buy used. They truly are a wonderful rv, but this is a very expnsive repair job, and only a few repair facilities can do it properly. Quotes easily run in the 8k range. So, if an A/S is in your plans, you have been warned.
