I have found the best way to increase mileage aside form what has already been mentioned is:
- Keep the RPM's under 2k at all times.
- Cruise Control on the highway ALL the time! Cruise control alone on the highway saves me gallons of fuel on every trip.
- Find the least traffic path to work. If you can maintain a constant speed, MPG's go up on any driving.
- Removing unwanted weight from your truck. My speakerbox, tools and misc gear alone is just over 200lbs. If you can get away with it, pull the spare tire for even great weight savings.

Or a sail!
That 100 pounds on a 6000 pound truck isn't going to make any measurable difference in mileage. Getting a flat and not having a spare would make for a real crappy day..or night.

Ok I'll reply. For a baseline on a 2 door 4x4 350/4L60e 3.42 with a true dual straight thru exhaust and Cold Air Intake I got around 18-20 on the highway. Not sure in town. Probably 12-15. It also had 31x10.50x 15 someone else installed. I am getting about the same with the same engine and stock air cleaner and cat back straight pipes with 2003 Tahoe 17" wheels and 245 tires in my 1993 Tahoe I replaced the Yukon with. On the hiway In 4th gear I get better mileage at 2000 rpms at 75 then driving between 55-65. Not sure why. In 180 miles i use roughly 3/8 of a tank at 75 versus 5/8 tank at around 60. Tune-up is the biggest thing.
