It’s not every day that TFLtruck gets an opportunity to compare similarly configured trucks, with the same load, and under conditions. The 2014 Ram 2500 HD Crew Cab 4×4 Big Horn you see here is $210 more expensive than the 2015 Chevy Silverado 2500 HD we  recently tested.

We had the same load behind both trucks. We adjusted the bed weight to compensate for the absence of Emme Hall, and the final weigh-in showed that the Ram and Chevy were within 100 pounds of each other for the Gross Combined Vehicle Weight (GCVW).

The weather was about the same. It was 72F during the Ram test, which was three degrees cooler than during the Chevy test.

The stage was set for the closest, most apples-to-apples HD truck comparison. However, the result was surprising. Check the data and the video below.
