I have a 03 2WD 4.8L 3.42 gearing. Around town with approx 700# of winter weight in the back I get 16 almost 17. Only took 1 trip unloaded and avg 20mpg. Funny thing is I once had a club cab with a 305 , 5 spd manual that got great mileage. The delaers say these motors are much more powerful than the old hence the lower mileage. Either way at the price of gas it sucks
