I have a 2011 Sierra with the 5.3 and use the tow/haul button when towing my 30 foot trail cruiser. I have found that the Sierra rarely goes into 6th gear (second overdrive gear) when towing anyway. When very hilly it hunts from 4th to 5th (first overdrive gear)and I manually lock out 5th and 6th gears when this occurs. Once the terrain changes again, I put it back into D and let the transmission act as designed.
Back when I was towing with my 2001 Sierra, I kept 4th gear (overdrive) locked out since my tow/haul button stopped working anyway and the truck really struggled in 4th gear.
With my Acadia I lock-out 5th and 6th gear when hilly, and I allow 5th gear when flat, but 6th gear towing really increases my fuel consumption in that vehicle.
I always tow in tow mode
