Very cool video, Joe.

PFB, the weight of anything you haul is not entirely supported by the trailer. Even with jeeps, some of the weight is still transfered to the tractor's 5th wheel, and that's key. Unless the lead jeep is pulled from a drawbar, like a wagon, the tractor will still have weight on it. Then you would need a weight box on the tractor. You probably would need less weight on the tractor, then one might think. Say something like 15 to 20 pounds of weight on the tractor's 5th wheel would probably be enough to pull 80 pounds gross. Depending how freewheeling the wheels are, and how stiff the tires might be.
