I went to the dealership on a Saturday and had one of the techs help me (we each had a side) put an OEM hitch on my X5 3.0/5 and I wouldn't suggest anything other than OEM, because the aftermarket ones just bolt on underneath but the OEM actually bolts right through into the to the area where the spare tire is stored, all parts needed were included from the rear bumper weight that needs to be changed right down to the 30A fuse to add into the panel. I was very surprised, and don't be afraid of the DIY instructions, they look intimidating, but once you get going it moves right along and everything actually makes sense as you're doing it also.
