Not a simple process. End result was great, but the tolerances on the hitch assembly were terrible. Had to pry thing 1/2 a bolt width in order to get things to line up. Overall, about a 3 hour job... and for a "bolt on" it should have been easier.

The "Vertical Hitch" is now installed and I found a Uni-Go adapter/receiver bracket that pops right in:

Attachment 25128

Now to wait for the weather to break and take a ride with the "pod" behind me.
(Still need to take care of the wiring, but there are a few, simple, third-party options for wiring - first I need to look at the stuff that came with the Uni-Go trailer).
