Art, would it be worth the $600 - $1000 to regear that beast of a truck (F550)?
or would it just take away too much torque and take too long to recoupe the
investment?

My F350 diesel (6.0) has 4:10 and 285/75R16 tires and seems to do about
9 to 12 mpg depending on how many hills we climb with a 7.5K load.
I suppose if I went back to the stock 265/75R16 tires that might help a bit.

But it's not capable of getting the kind of milage the Dodge diesles seem to
get at all.
