Reg Cab or Quad cab 03 or 04?

Not wanting to start any wars, but I was wondering which cab would get better fuel mileage as a rule of thumb, empty highway driving. Same bed / transmission/ drive tran. Or theres not a difference?

given the same drivetrain the smaller cab meaning less weight will require less power. My truck weighed in at 6560lbs I average 17-19 mixed driving and higher for long road trips

Yes, every thing else the same the lighter truck = better MPG

lighter truck will do better, but not THAT much better... the quad isn't much heavier than a single.



the rest of the combo makes a big difference... ride height, etc. aerodynamics is a huge factor at highway speeds

 

[AMcCormick]

theory will show the lighter vechile will get better mpg if the two are identical. There are lots of variables, tires, tuners, engine oil, tire pressure, gearing, lift etc etc etc

I m guessing here, correct me if Im wrong, reg cab may get a tick better MPG than quad cab but not much?
