All here is the link for Fords Towing Capacity Sheets for the 2011 F150s. The Raptor supercab is listed at the bottom of the page. 4x2 is rated at 6000lbs 4x4 is rated at 8000lbs. The Crews are not listed but will be compareable I'm sure.

Any other idea what screw will be able to tow? I can't find a definitive answer online. I want to buy one, but may have a couple time of towing my Factory Five car (2k lbs) in an enclosed trailer.
