After a couple of false starts, Atticus backs onto the trailer using a pedestal. I also had him back all the way to the breast bar so that he could feel it against his haunches. Then I had him come forward a couple of times and back again. Then I shaped him to come off the trailer forward using the pedestal. That part is in the next video.
