I may ve posted earlier about it but I can't find the thread.
But it's pretty simple.
I'm using the 2" receiver plate from Extreme.

Along with a receiver step from Harbor Freight. I had to cut off 1.625" so the extender would fit into the shallow receiver.

And the crane. I bought mine used from CL. This one might work:

These pickup bed cranes all have a swivel base. I started out with one, but it was hard to control so I eliminated it. Much better.
It's a bit floppy Left/right due to the loose fit in the receiver. Lifting the 3-pt drawbar fixes that. I intend to add some "outrigger" blocks to bear on the drawbar for better stability. If no 3-pt you could probably come up with a pair of stabilizing struts.
