Looks good already
I just got my 1st F150 (2002). Pretty much stock white-on-white, it looks like a before image of your truck. You already have some of the stuff I want.: Nerf bars, shell or hard bed cover (any thoughts?).
I like some of you ideas too. I was thinking 2" lift (subtle) but lighter aluminum wheels with only slightly bigger tires (good smooth rolling highway tires not mudders). All the intake/exhaust, drivetrain, suspension and tuning mods I have planned will be about good highway economy and performance.
I'll be keeping an eye on your build for ideas.
