its a double transfer case setup, i think this truck is setup for tug o war pulls and for the mudpit
and the bottom pic can be decieving with driveline angles and all that, some of the driveshaft are just hanging there, being supported by the red straps in the pictures, like i stated before, this truck is still under construction and is NOT final, so that suspension setup could be redone
and for comparison, that white wall in the background, is a good 10-12 ft tall, imagine how tall it will be on 66 inch terra tires
