This huge pickup was Nissan's first foray into this category, which is so popular in the U.S. Nissan is getting set to market the second generation, which has been updated from top to bottom and features a new bed and cabin. What's more, a heavy duty XD version will soon be offered, featuring a brand new 5.0L Cummins turbodiesel engine that generates 310 horsepower and 555 lb.-ft. of torque.
