The brand new 2015 GMC Sierra 3500 is a big diesel truck that’s made for towing and we put it to the test to see how it will manage towing over 15,000 pounds up one of America’s steepest highways in the Colorado Rockies. The Ike Gauntlet is a timed run from 9,000 feet above sea level to the top of the mountain at the entrance to the Eisenhower Tunnel in Colorado.
Check out this preview of what’s coming up soon on The Fast Lane Truck. You can also watch all other Ike Gauntlet videos.
Nicole Wakelin fell in love with cars as a teenager when she got to go for a ride in a Ferrari. It was red and it was fast and that was all that mattered. Game over. She considers things a bit more carefully now, but still has a weakness for fast, beautiful cars. Nicole also writes for NerdApproved and GeekMom.
