It's those big wheels and the valets cranking the wheel left and right, probably with the truck stationary that's killing your bushings.
While I have NO clue how big those bushings are, they do have that gap that I've seen on other GM vehicle rear end cradle bushings. Those wanting more performance-oriented drivers of those cars have updated the bushings, and/or used inserts that insert delrin into those open areas with little-to-no increase in NVH. Perhaps it's something to look at:
