-Excellent trailering mirrors with lights, allow increased visibility when backing up at night -Engine noise is relatively quiet compared to older diesel pick ups, can order at fast food drive throughs without shutting engine off -Fuel economy is good for a vehicle of this size (I have 3500HD, not 2500HD) -Driver safety features and various camera views are very helpful -Trim version for this review is Denali, with power running boards, really not missing anything significant
