great video, only suggestion would be to roll down your window while backing up, my driver instructor told me that when i started it has saved me quite a few times over the years being able to hear someone shout something at me, from shipper saying to move to a different door to one time a fork lift fell out of the building at the door i was 60% backed into. if the window was up i might not have heard they guys yelling to stop and saved me from crushing the guy.
