Recently ordered a truck as well, '15 GMC 1500. Crew, 4wd, 5.3 v8. I went with the 3.08 rear gear, which should really pay dividends on the highway.
Guys seem to be averaging 20+ mpg, even with shorter gearing. The cylinder deactivation makes a big difference. Wont be towing more than once or twice a year, so that's not a concern. Not really a truck guy but the gm seemed like the best value. $5000 for the diesel plus more expensive fuel, I'd never earn that back.
