I am thinking about getting a 2001 chevy 3/4ton extended cab 4x4 that has the 6.0 engine. I wanted to know if anyone has any real world fuel mileage results. I will not be towing during normal work times. I may have about 100 lbs of gear extra. Will be running around town 50% and Interstate the other 50%. I know it doesnt look like i need a 3/4 ton to haul 100lbs. But i do haul a heavy trailer 3 or 4 times a year over 400 miles so i do. I just want to see if the truck can be my main work truck and retire the Cherokee i am using now.
