I have revolvers on my 80. They are good and bad in their own ways. But like anything else it is more about learning aobut YOUR truck and how your setup reacts in different situations. I like the flex that the revolvers give... But yes... they can unload. I have semi solved this problem by using a single limiting strap in the middle of the rear end. that way one side or the other can fully extend but it does not allow them both to fully unload at the same time.
