Howdy ~ I'm wondering who is getting the best MPG? What modifications did you make to get there, and what was the total bill for those mods? Even though the "driving season" is over and gas prices have come down some what, I want to do some serious mods after spending $4/gallon all summer. My trip computer says I've averaged 13.6 over my first 30k miles in my '11 (split city, highway). This is my 3rd Armada, and I love it and will buy another, but that 13.6 has to change... Time to brag lads! Who's getting north of 18 mpg? north of 20 mpg? Thanks!
