To back something like that, it's comparable to backing up a hay wagon with steering on the front axle. Not hard once you remember that you turn the steering wheel in the direction you want the rear end to go.
This from a farm boy that knows
The chains were tight on both sides keeping it straight behind the truck and unable to pivot. You back exactly the same as you would normally back your 5r from what I was watching on the video.
Ahh. I did not watch the video. Just figured there was a second pivot point.
On edit...I watched the first few minutes of the video and the narrator refers to it having a steering axle, thus a second pivot point so it turns and follows the TV.
As for stopping, additional axle with, it appears, larger brake pads and drums than the average trailer and even the TV.
Just another inventor with a vision trying to market his idea...
