Koebe, My unit has some, I have had alot of it taken care of under warranty. My unit sat on the dealers lot for 14 months without much care. I think that with some regular attention and cleaning/waxing this can be limited to how quickly it spreads. My tailights and entry handle were just sick, now look good for the last two years.

It is an issue, however it does not keep me from enjoying my Airstream!!

Does your Safari have the corrosion? I have been told that it happens eventually on 90% of units? Is this true?
