I like this option "To aid nighttime loading, LED lighting available on Silverado (standard on Sierra) mounted under the bed rails."
Also noticed the Z71 package is using Rancho shocks, not bilstiens.
"On the safety front, the trucks tout available lane departure warning, forward collision warning systems, and backup camera, along with standard trailer sway control, hill start assist, side curtain air bags, and OnStar telematics." - I wonder how well these systems will play offroad.... or if you can turn them off.
You left out the Hill Descent Control........
