Hey Burt Gummer, Ford is testing out a truck that might finally be the perfect replacement for your K5 GMC Jimmy. The CarBuzz spies have spotted what might be the heaviest Tremor yet. It’s a Ford F-350 wearing a color we haven’t seen before and tires that put the super in Super Duty. This F-350 prototype is wearing 37-inch tires, showing that the Blue Oval is looking to make its big pickup even bigger and meaner than ever.
