Bones the jist is, Rhys Miller is going to backflip a truck at some Vegas Casino on New Years Eve. The vid is of him in a practice session with the ramp, and it cuts off right as he hits the ramp but they keep the audio going so you know he makes it.
The ramp is rather short, but transitions near verticle quick. The last 5-7ft though look like its seperate and that it is a springboard though you dont see that. I think they load it, and when the weight of the truck hits it it auto-unloads sending the truck cartwheeling.
