If you think 14.5 MPG at 78 MPH is bad mileage then you shouldn't buy one of these trucks. . . . .I drove a DRW with a flat bed today at the dealer. The wind noise off the rear window rack was very loud and according to the DCI the Fuel mileage was not very good to me. 14.5 MPG at 78 MPH on the highway with no load. Dealer is going to locate a 3500 SRW for me.
I have researched this some and like you mentioned it appears to me that the 3500 has overload springs on the rear. It's been a while since I looked at one, but the DRW might (I old and can't remember for sure) have an additional spring in the main spring packDoes anybody know the difference between 2500hd and 3500hd SRW from what i can see its just leaf spring pack and tires?
