The company I work part time for has a 2013 F350 flatbed that tows a 26" gooseneck flatbed and at 85K miles it dropped 3 glow plugs and blew the motor, Ford warrantyed the motor. The 6.0 F350 before that blew up also. When it comes to diesel trucks I wouldn't buy a Ford. Cummins or DMax are the way to go.
