MPG 20 or not

[DWPC]

Last weekend we drove from the LA area to Sedona AZ and got 17.9 mpg averaging 65+ mph with the a/c on. That's for an automatic with 5000 mi., Adventure pkg, brush guard, roof bars and std tire pressure on a route with a lot of long grades.

Based on that I think I could get really close to 20mpg if I turned off the a/c, upped the tire pressure and drove with max economy in mind; maybe even more.
