Looks like a clean bob except for the frame. The only way he could still have the frame stick out the back with a working tailgate is with a body lift. I would like the bob better if he kept the rear windows in the top - it would have gave it less blind spots.
Those fenders look tough, but what are they mounted to in the rear? If your going to do an exo, don't half ass it and attatch it to the body, give yourself some clearance from the body and attatch it to the frame or it will end up a twisted mess once you get some torsional flex in that frame.
