All - I'm getting a consistent 15 mpg in mixed suburban driving around Silicon Valley. I've only done one coastal highway trip (not all freeway) and got 18 mpg.

Hummer Jim - what speed did you generally cruise at when you got 18mpg. I plan to take some road trips later which means cruising at 80 mph in central California. What type of mileage should I expect?

firm - I'm not surprised that the base accelerates better on the street (in high range) because of the significant difference in tire diameter. Of course in low range the adventure package will accelerate and climb better because of the shorter gearing.
