Speed at 2000 RPM's?
I know that we all have diferent gearing in rears and maunual/auto transmissions. Being that 2000 RPM is the "magic number" for fuel economy and there have been a lot of threads on mileage lately, I just wanted to know at what speed everyone's trucks going at 2000 RPM's.
So, I have a dually, 4.10 rear, auto. level surface. 62MPH @ 2K RPM.
Just curious.

GeoffNJ, good thread. Suprised numbers are so uniform. It looks like driving habits is the largest factor in fuel mileage.
