I posted a picture here or on a ford truck website of what happens when you bolt a tow hook to the frame rail and attempt a serious pull. You bend the frame rail. When you bend the frame rail down, other things can move including your sway bar.
If I put tow hooks on, I run a piece of channel (U shape up with drain holes drilled) left to right inside the frame rail (bolt, hook, frame rail, 3/16" channel, washer, nut.) for the cleanest look.
If I do not care about looks (aka my own vehicle) I go with something such as this:
Probably the simplest way and cleanest way for most people is to install a heavy duty receiver hitch (10000#) and run a strap through the 2x2 tube to a 5/8" pin. They make adjustable front mount hitches too.
