we have a 05 gulf stream endura which we purchased at the beginning of this year and started having trouble with the large slide closing. then we noticed the tail in sagging and the doors on the bottom not lining up. we took it to a frame shop and the technician noticed our frame was sagging and stretching to where our leveling jacks were putting a dent in the fuel tank. this is a serious problem and began looking into it further and found our leveling jacks were welded to the frame which is a NO NO it says so in your info from chevy. if any one else has come across this problem please email @ email@example.com. we are in the process of trying to get gulf stream to take responsibilty for some of this repairs.
