2015 Sierra 1500 options
I am thinking about upgrading my current tow vehicle, a 2010 Sierra, to a new 2015 Sierra. My current and new truck are 4X4 crew cabs. Current truck has the 5.3 with 3.08 gears, towing with this truck...

Get the one with the most payload. I believe that is the NHT package which also includes the 3.73 axle. You'll never notice any fuel difference between the same truck and different gearing. You will notice the power.
