Maybe I misinterpreted your presentation, but rear end separation is usually observed when weight is applied to the top of the bumper, and watching the frame it is connected to separate from the shell.
Regardless, you need to read Airstream's Bulletin #29 which addresses this problem. You will see that their fix is totally different than what you have in mind.
I printed that bulletin from the web some months ago, but cannot seem to find the link today. Perhaps someone else can point to it.
might help you
