2007 Chevy 2500HD Crew mileage
Hi every one. I just completed a 567 mile round trip and the mileage was around 7.4 mpg. Empty around town or highway, im seeing 11 mpg. I'm starting to wonder if new plugs and wires are in...

Your fuel mileage is right on the mark for the 6.0. Nothing to worry about. If the truck has never had plugs/wires replaced then it's due but your fuel mileage will probably not increase.
