I saw this as well, they truly did think of almost everything. You put your TC in the back of it, if you didn't know that already. Trouble is the cost. I called them and a basic unit without all the extras, of which there are many, was $12K. That is in the ballpark for a custom made utility bed.
This unit is a bit more versatile than a utility bed, but personally I wouldn't want to sink that kind of money in truck that I would have to part with if and when I sold that truck.
