Having owned four 4wd vehicles, and waiting for my OR to arrive this week, the rear locker alone is worth the cost difference. If you get into a jam, engage it and you can move out of a situation that would otherwise have cost you the money of an off-road tow and the hours (days?) of waiting for someone with a winch. The price difference just paid for itself. The shocks, plates, tires, HA and HD are all items that will protect you, even in "mild" off-roading. IMHO.
