Sue, it definitely sounds like Keystone should cover your repair. But I think John and Greg gave you bad advice. The factory tour isn't the place/setting to take up issues with Keystone. From our experience, the tours are not even led by the people that you want to talk to. We had a great experience with Darryl and George at the Service Center and you'd probably have better luck with them. They should be available during your stay at the rally.
