I installed the Trailer Tow Hitch in my 2006 Ford Explorer XLS.
It fit perfectly, the installation took me no more than two hours and I used only two wrenches (19mm for lower the spare tire and to tighten the nuts of the trailer tow hitch, 13mm to loosen the nut of the trailer electrical connector).
Excellent quality, perfect finishes.
The installation instructions are very clear.
The only difficult thing is to pass the bolts with the steel wire inside the frame of the vehicle, it just takes patience.
