While installing my splash gaurds I noticed that the tire to gaurd clearance was different from one side to the other. Then measured the clearance between the bed and the cab to find nearly a 1/2" difference from driver to passenger side. Anybody else noticed this? The truck is new/never wrecked with 6K mi.

 

The dealer should be able to adjust this for you. I thought I remembered seeing a post on this before.
