Hello & Welcome Bench:
I do not know anything about the Air Force One but I do have an M&G brake system. I have used it on two Suburban's and now on the Yukon. I found it to work Great. The installation I did not have too connect any electrical power the M&G to get to operate either on the coach or towed vehicle. The only electrical would be to an air compressor installation on the coach only if your coach needs an air compressor.
When I connect the car all I connect is the air hose and the system is up and working and no draw to electrical on the Yukon. I have seen most of the brake systems and they all appear to work just fine.
It all depends on what you like.
