Hi, Right now I have a Sport Trac with a 6" lift and running 33's. My gas mileage is really horrible like 12mpg. I was wondering in a year or so I want to buy a 00-02 Ext. cab sierra with the 5.3L V8. I was wondering for all you guys running lifts whats your gas mileage like? I want to run probably only a body lift or if anything a minor suspension lift with 33's or 35's on 15x10's. So if you guys can pitch in and tell me what your gas mileage is like that'd be great thanks.
