The data from The Fast Lane Truck’s first Ike Gauntlet – Light Duty edition is in.  Here is the summary of the results so you can see it all in one place.  This extreme towing test saw the following three pickups: 2013 Toyota Tundra CrewMax 4×4 Limited TRD Off-Road, 2013 Ford F-150 SuperCrew Ecoboost 4×4 Limited, and 2014 Chevrolet Silverado Crew Cab 4×4 Z71.

This extreme test is designed to showcase how the truck cope with towing a load, which is 85% or higher of their maximum tow rating, at high elevation and up a steep grade.  The Ike Gauntlet is going down and up the eight mile stretch of interstate I-70 between the Eisenhower/Johnson Memorial Tunnel and the town of Silverthorn.  There is more than 3,000 feet of elevation change with an average 7% grade.  The finish line is at 11,158 feet above sea level!
