rear axle ratios
Any suggestions on the following rear axel options, on a 2011 F250 diesel crew cab 4x4? The one that comes with the truck I'm looking at is the 3.55. What would be the optimum for fuel economy?
Thanks

A 250 diesel is going to be used to haul or tow something. What is it, how often and over what terrain?

It would be pulling a 27' AS International.

3.55 works fine for us. Truck pulls with no strain whatsoever.
