When I went from a 2006 to 2012 Silverado, the bed went up an inch (if I remember right) and the rails another 1 or 1 1/2 inches. So my rig is about 3 inches high at the front, but seems to handle okay. Oh, I think I had to raise the hitch or lower the trailer hitch a bit also.
Maybe Ford is just finally raising the height?? If they did it 4-5 years ago also, they must REALLY think people are getting tall!!!
