Is that the same as adaptive cruise control? My last coach had Eaton Vorad ACC and I liked it very much, it was smooth. It would operate the engine brake but not the service brakes. My pickup truck has ACC but it is abrupt, not smooth at all. I guess it's impossible to do anything abrupt with a heavy coach. Let us know what you find out, it may be as simple as adding the radar antenna and plugging the controller into the J1939.
