( http://www.TFLtruck.com ) The 2014 GMC Sierra 5.3L and the Nissan Titan and the Chevy Silverado 6.2L are three lite duty trucks that compete in today's super-heated truck wars. The 2014 GMC Sierra 5.3L and the Chevy Silverado 6.2L are completely new while the Nissan Titan soldiers on since it was first introduced in 2004. We wanted to find out how these new trucks stack up against the older Nissan and how they stack up against each other. In another fun and informative TFLtruck video review we decided to find out which of these three trucks is the fastest from 0-60 MPH and which one is fastest towing the TFL test boat from 0-60 MPH. In this Part 1 of our second ultimate matchup towing challenge we start by testing the new 2014 GMC Sierra 5.3L from 0-60 MPH.
