I am assuming you removed your sex bolt? They come from the factory with one in place. If unneeded let DR know and they will save a bundle over the course of the next several years....
The sex bolt simply holds the wing to the Pac when a tank is not in place. It does not serve as a load bearing piece of hardware.
Cam straps hold the tank to the Pac. It sounds more likely you assembled your gear incorrectly. But I wasn't there.
