Traded my 2014 Sierra Z71 5.3 crew cab, for a 2015 Z71 5.3 Double Cab, with all the same options. Main reason I dropped down to a Double Cab was because it was built in Ft. Wayne. The trucks are basically the same, but IMO the build quality is much better in the Double Cab. I agree 100% with other Double Cab owners-Great Job Ft. Wayne! Love the truck!
