It was simply a YouTube video I found from 2010. There is no attached information about it. And that channel hasn't posted anything in years. It would be cool to find out how it did it to replicate it. Because, unless I buy a trailer, its going to be too much of a pain in the butt to try and load and unload from the truck bed each time. With this, I wouldn't have to wait for the wife, or inconvenience anyone else.
