Re: Better MPG

The lowering for reduced wind resistance will be the biggest benefit.
Preventing air from rushing under the truck is the biggest thing you can do
to improve your truck's aerodynamics (yep, even more than a good tonneau
cover!). Lower it, then add a good ground-effects package.

As far as handling, that will depend on how good of a kit you get installed.
A poor kit will actually make your truck handle worse. Personally, I just
lowered my truck an inch by putting on shorter tires (with bicycle computer
to correct speedometer); therefore, I've maintained all factory geometry and
suspension clearance, with improved handling simply from a lower center of
gravity.

MPG with the shorter tires has equaled that of the taller tires - I think
this is because 1) around town, the shorter tires make for shorter effective
gearing, allowing less engine to be used at stoplights, and 2) the mpg
gained (thru aerodynamics) from lowering the truck offsets the lower
effective gearing (I think my 3.55 is effectively a 3.9x) at highway speeds.
