I too, like X5turtle noticed that the gap distance between the bumber and rear hatch was off by about an quarter of an inch after I installed my hitch. I'm sure this was due to play in the mounting holes of the various pieces. I know I could loosen and retighten the pieces to remove this gap but no one would notice but me. My advice to anyone else doing their hitch would be to be aware of this and keep an eye on the play in the pieces when assembling the hitch.
