Yes you are correct about the maximum towing capacity for a properly equipped vehicle. Mine is a 4x4 Supercrew which I believe is rated at 9200. SuperCrew and 4x4 take away from max towing, also what gear ratio you have in the rear end. You need the 4.11 to get the max and that does not come in all vehicles.

Also doesn't it void your warranty to exceed the numbers listed in the manual? So if the "real" numbers are higher is Ford going to put something up other than just a blurb in the press?
I suppose it voids the warr. if you overlaod it but how are they going to tell. Ford did update the max tow capacity, check out the max for the regular cab 4x2 long bed with 4.10 and 5.4L it is now 9900. Again if you need to tow this weight then I would go with the superduty as APT says. Maybe a guy needs both trucks one for towing and one for cruising. That sounds good to me. A man cannot have too many trucks!
