I wanted to update this thread with some information. I had the dealer fixing my slide out motor (replaced) and while he had it, I took the stable-loads off the truck because I was pretty much done for the season, and they give a harsh ride on the miles of dirt roads I drive. So the story is that I picked up the camper WITHOUT them installed, and the ride was amazing. No bounce whatsoever. So I am convinced that these stable-loads are root of the issue causing the bounce. As stated, they nearly flatten the helpers to near horizontal.
So my next move is to cut them down a couple inches, to retain some of the value they may provide in roll.
That's all.
