[Fulltiming]

Back in the old days when I had Airstream travel trailers, I had a double wheel Power Caster PC-3 that I used to move my trailer around. That one was limited to 1800 pounds of tongue weight and although it moved my almost 10,000 pound trailer around, I doubt it would move a trailer much heavier than that.

Trailer tugs that will handle 20,000+ pound loads ups the game. Airtug and DJ Products make units that will move heavier loads.
