We had the same problem coming back from Alaska last year. Stopped in Coburg, Oregon camping world. They said the screws underneath on the outside had worked their way loose. They riveted everything back together and lined up the slide. Didn't cost anything. Was under Warrenty. We've put on maybe 10,000 miles and it's been good since it's been fixed. This time cudoo's go to that Camping World.
