I went with an M&G system. I plan to keep my tow jeep longer than my gas coach, so the M&G system is an air system in the Jeep, and a hydraulic to air converter (for lack of better term) in the coach, so all I hook up is an air hose.
When I upgrade to a diesel pusher with air brakes in a year or two, then the Jeep is good to go and I'll just hook up my air hose.
