Remembered why I got a F450 with 4.30 gears ... observation.

Eagle,
Is that van 4WD? I don't see any diff hump on the front axle.
Very nice looking rig.
Gearing is a very subjective thing. There are so many things that are in play including the age and driving style. Even when you think you are dealing with absolutes....you are not. For once in my life, my gearing change worked out better than I thought it would even after crunching all the numbers and contingencies. So, I don't get too lathered up about others' findings. After all, they are there own, not yours.
