i got 256k and get anywhere from 14-17. I just put a new radiatior in it and that boosted my power, the truck pulls much stronger up hills. Im thinking about getting a new thermostat because i have a feeling mine is pretty old, and that would prolly boost my mileage. Erik, i just ordered up some 35's bfg km2 with rims. ill post a pic when i get them <img src="/forums/images/graemlins/cheers.gif" alt="" />
