This truck is by far the most reliable of them yet. Maybe after a few years then new F-150's will bypass the milestone Ford has set for the reliability of its F-150 models.
Everything except the 2WD grille and bumper.
Put some bigger tires on it. Look into better wheel styles. Keep the front ends the same, I have many problems when ordering parts with different grille styles, different bumpers. I don't know why they had to change the bumper and grille so that the 4WD and 2WD are different.
