Very cool, but if I had $2300 to blow it sure wouldn't be on this. I'll bet that system would move a TT up on leveling blocks; the factory tongue jack would be fine for paved areas but I'll bet those casters would get jammed up on a lawn or unpaved area. Those 4 powerful motors must eat the juice though....I wonder how far you could maneuver a TT with 2 12v batteries onboard? And I'll bet the setup adds a lot of weight to the TT also.
I would think you would be better off with a quality set of towing mirrors...with this remote setup, you would constantly be walking back and forth to see both sides of the TT while you are backing. With good mirrors, you can see both sides from the driver's seat and back the TT more efficiently.
Tatonka is there a specific need for where you park your TT that you are considering these?
