I just order a 2014 JGC Summit with the Diesel motor. I had three options to pick; 1) Engine Heater 2) CD Player 3) DVD Player. I picked the engine heater and did not want the other two. I just want to make sure I am not missing any other options. It is my understanding this trim package comes with the trailer receiver and all wiring etc.. I guess I don't want any surprises.
