I have the M&G system. I have used it on two coaches. It has been flawless and invisible. I installed the breakaway kit also.

I tapped into one of the tag brake lines for the M&G supply line. Also made a small bracket for the hitch to hold the end of the supply line. Installation on the coach is an hour, if you take a nap halfway through. It took me a little longer on the Subie because I had to disconnect the hyd brake lines from the master cylinder to the get the M&G pneumatic cylinder in place. That meant I had to bleed the brakes when I put the lines back in the master cylinder.

I would recommend this system without reservation.
