So far the bed caps and toolbox, but I've only had it a month. I guess since 2011 was the last year, Ford decided to cut cost and leave the caps off. My other tow had them from the factory, but they cost more too. lol

 

The "Foglight Mod" was by far the best cost effective mod you can do !

Increased the high-beam light pattern 100%, filled in by the front of the truck, really good mod; surprised me !

Then there is the lift, the grille, the swap to a steppie (gotta love that one too), the tires and wheels and I would like to say the 5.0 mod but that’s not done yet.

Oh ya, sorry you said the best mod, that means one, doesn’t it !

 

I'd say the truck itself.
