( http://www.TFLtruck.com ) The 2015 Ram 2500 Cummins looks mean in all black. This is the Laramie package 4×2 with the RamBox. The 6.7L I6 Cummins lurks under the black hood. In this configuration it makes 370 horsepower and 800 lb-ft of torque. This model also has air suspension on the rear axle.
How does it compare to the GMC Duramax when towing the same trailer up the extreme Ike Gauntlet hill on I-70 in Colorado? Watch this to find out.
The Ike Gauntlet is a timed run up one of America’s steepest highways from 9,000 feet above sea level to the top of the mountain at entrance to the Eisenhower Tunnel in Colorado.
