On the Ram, the cruise control also can operate the engine brake, and depending on the weight of the trailer you get, might not need any standard brake application once engaged.
Myself, personally, I don't want a computer deciding when and how much to apply the brakes in everyday driving. If something goes wrong with that system, I'd be very unhappy if it suddenly decided I needed full brake application at the wrong time. I'm not a trusting early adopter.
