Not so much for the OP but for anybody that might look at this thread, when buying a Ford always, always, always get the tow package even if you don't intend to tow anything. Why? Well...
1) Life happens and you might find yourself with a boat (or fill in the blank) you never expected to get,
2) It helps with resale, and (the big one),
3) In almost every case, adding a tow package adds more than just a factory receiver hitch.
There's some combination/permutation of about a dozen things that can be done at the factory to increase towing capacity including bigger radiator/grill, oil cooler, transmission cooler, beefier transmission, power steering cooler, transmission tuning (normally done through electronics now), heavy-duty brakes, better suspension, differential drive ratios, upgraded battery/alternator, necessary wiring, etc.
My point is that the extra $500 to $700 for the tow package is just about the best bargain available in Ford Packages. All, except for the wiring, of these upgrades will make your vehicle last longer and be more rugged and reliable. For almost everyone that's worth the cost of the upgrade.
