how the hell do i do a half cab triple truck driver

okay go to the place you do it and there is a slope leading to it, try and stop at the sop so you are facing away from the ramp, now you will start to roll backwards. a triple truck triive ir doing 3 barspins while you spin 360* and doin it half-cab means doing it backward, so when you get to the ramp going backwards just do the trick!!!
