Here are the pictures of my 3400RL after it was repaired because of a line crack along the side of the upper BR pull out. right side corner of the main body on the coach:

I would have made it an actual link, but don't know how. Take a good look how they cross-braced the front hitch, and used angle iron for the corners. They are also adding additional wood braces to the sides of the coach up where the stress crack is. I am trying to get them to replace the damaged crack, which would require replacing the whole side of the coach, still working that issue. To put the wood braces in, the service manager told me he would have to take the whole roof off, and replace it also. He was waiting to hear back fro Keystone. Will keep you all up todate.
