Some people shorten the box on the back and cut off the back axle so it is just a 4x4. That means a lighter more maneuverable vehicle that is also more efficient. Of course it will reduce the amount and weight of the payload (but that thing still hauls twice what a standard pick up would) and it would take some work to get it that way, but it is an option if you just don't want that much truck.
