That's the craziest maneuverability with a trailer that I've ever seen.
Such an unconventional way to attach a trailer that it made my brain hurt to watch him twist the tow vehicle under the hitch and do a 360 with the tow vehicle.
In one of his maneuvers, the "Trailer" became a "Preceder" or "Leader" if you prefer. It wasn't trailing him at all!
Weird, novel idea. Seems strange that this design went absolutely nowhere at all.
Good post. Nice find.
