Tasteful, upsized wheels and tires, SLIGHTLY lowered or raised stance (versus the belly dragging the ground or need for a ladder to get in it) and a nice sounding exaust system would make for a great truck.
The "please don't" list:
Billet grilles, fake scoops / vents, windshield visors, wheel arch / running board combinations without widening the track of the truck, extreme lowering or raising, obnoxious exausts, overdone decaling / striping, chromed everything, tractor tires, tonneau covers with integrated wing spoilers, Corvette-style taillights in the rear bumper, shaved door handles, LED ground lighting.
