----- 1/15/09 ----- It depends on which engine it has, gas or diesel. Generally speaking the diesel will get better gas mileage, but has higher fuel and maintenance costs. Need more info.......... (which engine, automatic or manual transmission)
It gets about 9 or 10 miles to the gallon in town or interstate!
It depends on body style(regular cab, extended, crew), 2 or 4wd, SRW(single rear wheel) or Dually, short/long bed and most important gas or diesel( diesel is 1,000lbs heavier). The heaviest a 4 door dually/ long bed 4x4 diesel has a curb weight of 8,220lbs. The lightest model for comparison, (regular cab, 2wd, srw, gasoline) weighs 5,808lbs.
That is a GAS engine.
