I have a 2012 Ford F-150 truck and my paint is chipping off.
Your truck is 8 years old. Buy some touchup paint from Ford or over the internet and fix the chips.
The only car I gave ever seen that was impervious to stone chips was a Delorean.
Manufacturers were changing their paint formulas in that time frame, to make the paint more environmentally friendly. Maybe has something to do w/that. If so the only solution other than touching it up and otherwise living w/the problem is to repaint the truck. Whatever the paint formulation problems were have likely been solved by now. You might want to ask at a Ford dealership if there’s any tsbs on the paint for this make/model/year.
