The F-450 isn’t as customizable as some of the lighter-duty pick-ups. Only the shortest and longest wheelbases are available, either 141.6 inches or 176 inches, along with the longer eight-foot cargo bed, giving the truck an overall length of between 231.8 inches and 266.2 inches. The strongest Super Duty stands tall at around 82 inches and wider than most at 105.9 inches with mirrors. When necessary, the truck can go off-road with its 8.6-inch ground clearance. By comparison, the Ram Super Duty is lifted higher off the ground with a maximum ground clearance figure of 13.1 inches. but the angles of approach and departure aren’t that impressive – 18.5 – 19 degrees and 18.3 – 21.6 degrees, respectively. You’ll be hard-pressed to find a heavier vehicle on the road, with the lightest F-450 weighing in at 7,712 pounds, while the heaviest tips the scale at a whopping 8,587 lbs.
