Making progress and just discovered another interference: The under bed spare carrier brace is occupying the offset hole (aligned with the 5th side strip hole from the front). I added the carrier according to the FAM . Perhaps the two can share a bolt? There is another similiar hole a few inches further down, close to the frame crossmember, I could use. But then the wood bolts on the cross sill wouldn't' line up. Or, move the spare carrier further down the frame?
EDIT: Moved the spare tire carrier towards the rear of the frame. All is good now!
