I have a 2014 CC standard bed 5.3 w/3.08 gears and actually towed something, I was towing a car on a trailer. Weight of car was right at 4300 +/- 100 pounds plus 2200 lbs for car trailer, full tank of gas,tool box on trailer with another 100 pounds, so I was damn near tipping the max of what the trailering guide says and was on anything but flat ground in WA also into stop and go traffic on the highway. All I did was put it in tow mode and set the cruise, my opinion- it does fine it didn't search for gears, shifted down on hills and did what it was designed to do. All in all I would say it could easily take another 1000 pounds safely, beyond that it would be a little tough for the pickup. Temp outside was between 55-70 degrees,Trans temp never got over 199 stayed right around 194, engine temp stayed right under 210. So for the people that tow in the less than often category it is fine. I would also like to mention I still am running stock tire size and also it is still 100 % stock
