Here is a clearer picture of the hub and latch

I love this idea, I've actually been thinking about building a fully articulated heavy duty trailer hitch useing a semi truck u-joint for lateral X-Y movement and a hub like that for rotational twist... I have it more or less figured out in my head but haven't drawn it out or given real serious thought yet. I just like the idea.
I have a buddy with an old 50's airstream that I can pick up for song. It's gutted and has no glass so you can imagine the interior condition, it's in SoCal so not that bad but still it would be a complete reconstruction/remodel. It's only 15 feet long. If I do get it, I'll lift it, put a truck axel underneath and some 33's! It would be more of a base camp bunk house than a full blown trail caboose.
