if you can skinnier tall tires
Fourth, a plastic body-pan thing underneath most of the vehicle
I'm wondering if anyone here has experience with these SUVs, because at first glance, they don't seem to be the least aerodynamically efficient vehicles, and yet the MPGs is terrible! So I wonder if I can hope for any gains at all with aero mods, or if I should just go with something more ambitious like:
Sixth: Engine swap (maybe a 3.3 or 3.9 cummins, with the right drivetrain)
Any thoughts would be appreciated.

which engine do you have?(4.7,5.2,5.9)
well at least you didn't get the 4x4 version my brother has. I have airtabs on my jeep; they cost me 40km per tank last summer when i put them on, though they do increase my coasting distance/speed; i think.
ps. if you have a luggage rack remove it
