Good pics Dave but of course now I have more questions.
In the picture of the contents laid out on the table, there appears to be a case, or some such thing, to the left of the Zumo. What is that, a carrying case?
And it is difficult to determine whether or not it is quick detachable. It appears to be solidly mounted to the bracket with two screws/nuts. I would think it would have a quick disconnect so that one could slip the box into his pocket during chow stops.
