Need advice on moving a fifth wheel without a truck

I've been eyeballing our airplane mover for our Bonanza as a starting concept, but still have to figure out a plan to carry the pin weight. I also want to transfer the push/pull force to the trailer frame, instead of it all being in the vertical (maybe that doesn't matter.). Finally, I really would like to overcome the force the user in the posted youtube video had to apply to turn the dolly.
Other than that, no problem! :)
