Heavy-duty pickups are found in one of the most competitive segments in the automotive industry. After being tested by PickupTrucks.com, GMC Sierra MI trucks have taken the lead from Ford and Ram trucks of similar sizes. MI Auto Times reports the details.

DETROIT, M.I. – GMC Sierra MI trucks were pinned against Ford and Ram trucks to test towing capacity and ultimate ability. The trucks covered 2,200 miles and towed trailers with cargo to prove the final and overall best heavy duty truck.

GMC Sierra fans may be happy to hear that the 2012 GMC Sierra 3500HD has taken first place as the Best Overall Truck by PickupTrucks.com.

From July 11 to 18, PickupTrucks.com tested three different trucks:

Each truck has to endure rigorous towing tests to show the maximum fifth-wheel towing, conventional towing and payload capacity.

“We procured similarly equipped trucks from Ford, Ram and GMC and put them through the paces, towing up and down some of the toughest grades in the country covering a total of 2,200 miles,” said Mike Levine, editor of PickupTrucks.com, in a GM press release. “When we analyzed the data, the GMC Sierra 3500HD simply outperformed the trucks from Ford and Ram.”

The Gross Combined Weight Rating (GCWR) was also factored into the results as the data was analyzed and GMC Sierra MI trucks named the winner.
