Be interesting to hear what it is like. My major concern is balance. I have tried a two wheel dolly and it required constant pressure to balance the trailer on the ball. Possibly that screw that raises into the ball will help.
For a drive/drill adapter I use
this and
this .
I can see that this one would be handy for multiple trailers and should be able able to turn over 180 degrees (frame mount is limited in some turns) but am concerned about the rigidity, ability on dirt/sandy soil, and how to carry it.
Please let us know how it works
