repair side wall with a stress/expansion joint

Thanks to everyone for your info.
1. The crack is just forward of the big slide on the left side.
2. I would love to see some pictures of your work.
2. If you have a web site for the Montana's that shows the stress point repairs, please let me know.
I presently have it in a body shop for installation of a expansion joint. If this works great, if it doesn't I don't know what to do next.
Thanks Wayne
