We own a Class C Gulfstream and are having some trouble and are looking to see if anyone else has had this trouble and how they may have solved it. We have a terrible squeak above the passenger door caused by separation of the coach from the front cabin.; We had it repaired? in Wlikins, NY ...they pushed the cabin with a tractor and screwed two large screws into the cabin wall. We are full timers and after more miles....the screws have backed out again..... Any suggestions, help or comments welcome.
