general socket set, mm of course. You have to take off the crash bar in the back and those bolts are on there pretty tight so maybe a breaker. Also you may need a few deep sockets for the bumper bolts. I think 13mm?
flat head screw driver to get those plastic clips off
phillips head to get the tail lights off
torque wrench for the hitch bolts (if you don't have one just get those suckers on tight)
nothing else really, just take your time so you don't break anything plastic.
