Hi Emo, thanks for the comments. I've thought about lowering the truck some for as long as I've owned it, just to make it easier to get in and out. I'm 5'9" and it is just high enough that I cannot step directly into the truck, I have to use the step rail to get in and usually to get out as well. Mine is 2WD and has the rake, the 4WD's of the same generation are the same height in the back and enough higher in the front to be level. I'm "assuming" that given how much ground clearance there is, a little lowering has to be good simply from cutting the frontal area, but it will all be bolt on and reversible if need be. I guess I'm thinking that the faster you go the more important aero is and the greater the percentage gain from a mod. Then you multiply that bigger gain times a smaller initial mpg and you may or may not get a bigger actual mpg change, but of course I'm hoping for the best. If you gain 2% at 60 mph and start at 22 mpg the gain is 0.4 mpg, and if you gain 6% at 75 and start at 16 mpg the gain is 0.96 mpg. Ok, 2-4 was wildly optimistic; it was way past my bedtime :-). I will definitely be reading that thread, it's just that there is so much good stuff I haven't gotten there yet.
