You didn't mention the Duramax being on your Denali order, so I'm assuming you'll be getting the 6.2L. Keep in mind that without Max Tow, you won't have the heavy duty radiator and your towing capacity is reduced. With the Duramax the towing capacity stays the same with or without Max Tow.
Outside of the 2-speed transfer case, all of the other parts of the package have aftermarket options (trailer pressure sensors and trailer brake controller).
