I have installed the following,
87436 Class III Hitch - Suzuki Xl7
118432 T-one Wiring Harness - Equinox
Bumper Guard
Ballmount Class Iii 2" Drop 9" Long No Pc3
Ball 1-7/8x1x2-1/8
Lock, Class Iii Bent Pin With Push Button
bought from etrailer.com shipped for less than $200. It took me about two hours to install but I am really anal, I locktited every bolt and did it myself without ANY help. I only tow a 500 lbs Aprilia scooter about once a year but where I live we get a lot of tourist and that hitch hanging behind the XL7 is a deterrent for tourist that want to get too close to my rear bumper. I will take pics and post tonight.
There you go:
