Silverado 2500 v 3500 fuel mileage ?
Like we buy these for fuel saving but . . . Has anyone who's owned both noticed any difference in fuel mileage between a Duramax in a 2500 and a Duramax in a 3500 frame?

I have owned both 2500 and 3500 (not dually). Mileage will be the same if both Dmax. If dually, I don't know but I assume a bit less due to addl weight and more tires.
