There was a recent thread by someone who had a lift kit of some kind installed by a dealer and the interior of their new Airstream nearly self-destructed within 10 miles of gravel road. Dealer said file an insurance claim. I don't have the link, maybe someone does.
It may be good to approach suspension mod's with caution, there may be trade-offs, warranty issues, and the installer should know what they are doing.
