So I parked my 2015 XLT sport in even ground with a 2013 4x4 XTR and yes it is higher cab height. Does anyone know what the size difference overall is, Height, Width and clearance. Maybe any more if you know.

 

The 2015 MY and 2012 MY are the same overall height, both standard spec 4x4 short box at 76.7 inches (per Ford published spec) HOWEVER the 2015 MY overall width w/o mirrors is WIDER at 79.7 inches vs 79.2 for the 2012 MY (again per Ford published spec) Options, including 4x4 vs 4x2, suspension options and tire options will affect overall height as will production tolerances from vehicle to vehicle.
