( http://www.TFLcar.com ) The 2011 GMC Sierra Denali 2500 4WD Crew Cab will go from 0-60 in just over 7 seconds. It will also tow 16,800 pounds and cargo bed will carry over 2500 pounds of payload. That's pretty amazing for a full sized pick-up. But is it better than the Ford or the Dodge? Watch the video and find out.
