On the trucks side, here is a cool one… The Turtle V
It was built using Ford F550 chassis on which an aluminum exoskeleton was welded and attached to the frame rails using a three-point suspension system copied from European campers. 1 1/2-inch Nida Core panels were then attached to the aluminum frame using a Sikaflex marine adhesive.

Now if you have money coming out of your ears and want to be completely over the top, here is the MaxiMog.
A cool 13,240 lbs for the rig and another 14,000 lbs for the trailer
