You've got duty? You ain't got duty until you've got Super freakin' duty. Try to strap on a Northward Grizzly Bear brand fifth-wheel camper trailer with optional slide-out forest-creature slaughterhouse and whiskey still to one of those reg'lar-duty trucks. Ain't gonna happen, my friend. Check out Ford's next F350 for those who love their duty.
