Forgot to add the 265x75x16 BFG KO all terrains mounted on the factory spare carrier (without a spare tire cover)did allow the rear door to open and close just fine. The spare rubbed ever so slightly on the rear bumper cover but it was not and issue. I ended up making an adapter plate myself anyway in caseI ever get around to a spare tire cover.

 

I just put on the 779 front and 763 rear set up... truck sits very nice, andI am very pleased with the ride. While the 751 will fit a series II, I can't imagine another inch up front. This set up (779/763)will support a bumper and winch set up with no problems.
