I flat towed the red COE truck from Washington State to New York, no problems... but

You will need a serious truck to be the lead dog.
If I had tried it with a 3/4 or 1 ton it would have been fun, and not very safe.

The ford I used I had previously updated with huge disc brakes from a Freightliner and a Chevy Top-Kick, the truck weighed 10,000 lb empty, and I had over 3,000 lb extra in the bed, and it had about a 300 hp diesel.
The big brakes were absolutely necessary, and even at that I crawled down some of the bigger mountains (on the interstate) at 25 mph, even slower going up.
The substantial weight of the lead truck helped to keep everything pointed east. If I had less weight the tailing truck would have really pushed me around. Near the end of the trip I unloaded the 3,000 lb I had in my bed, and there was a noticeable difference in how the red truck pushed me around, not a good thing.
The combination of HP and good gear choices (10 speeds) was also helpful. At times on the highway going over a bump or bridge things would start to wiggle a bit, a brief application of fuel would straighten everything out right away. Having closely spaced gears helped to get moving without to much effort.

Your best bet is to use a stout enough trailer with good brakes, and a suitable truck.
The tow bar may be fine if you have a serious lead truck and are careful. Although it is really only good for going in straight lines, and takes turns badly, and really wide.
