Invention award of the month.

Well, it seems like it has a nice wide wheelbase, but I would feel better about it if it we're level. It appears he just needs to drop the hitch a bit. My only other question would be where the center of gravity would be located. Could be a little high, but it appears he's custom built it just for that rig. He must have that thing lashed on there good. Edit- I watched the video and saw the two point attach. Very clever little self steering unit.
