A 3" body lift is cheap but it can be complicated as far as fan to radiator clearance, Shifter linkage, radiator hoses, brake lines, steering shaft, and that unsightly gap that shows up under the bed when you raise it up. I'm not going to say not to use a body lift, but I personally will not go higher than a 1" on my truck to keep clearance issues to a minimum. And you aren't going to need to put girls on your shoulders to put them in a F-150 with a 3" body lift.
