I have a halftrack that I want to haul around. Am considering buying a deuce and a tag trailer like a 10 ton backhoe trailer(interstate, zieman, miller, etc.) with air brakes. Anyone done this? Correct me if wrong, but I think deuce has service gladhand that gives modulated air for service brakes(0 pressure normally, harder step on brakes, more air pressure at gladhand) and an emergency gladhand that has full pressure at all times. I think air brake trailers have modulated service brakes and spring brakes for emergency/parking. Apply air to spring brakes and they release. If I am correct, then service brakes should work fine, but for spring brakes you would have to connect gladhands, then turn on valve on truck at emergency airline. When parking truck, would have to turn off truck emergency airline valve and then break connection at gladhand to dump air in spring brakes. If this correct, could I replumb airlines so that emergency airline in not constantly pressured, but is pressurized by a parking brake valve that is added to the dashboard like on a big-rig? Also, how do I connect the trailer plugs? Are male plugs available to fit socket in deuce? Does deuce send 12V or 24V to trailer lights? Any thoughts on this being good idea-trailer probably weighs 5-6K, halftrack 16K so towing over 20k load. Thanks for advice.
