Re: GAS MPG
I have the adventure model, and I average 18 mpg all day long. I do not check miliage with every tank, but I have checked 4 or 5 tanks and it averages 18 everytime. That is mostly highway, and little traffic.

Wow 18mpg, must be some slow highway speeds. Takes more self-restraint than I have to drive that slow. I've only seen 18 mpg once in 29000 miles of driving my H3. But freeway speeds in much of California are 75-90 mph.

I guess, I usually cruise the hwy at 70, if that is slow.
70 just feels like the right speed for the rig rpms are about 2200,
and it doesnt have to work hard to maintain it.

Couple of secrets...
DON'T drive it like a tank
DON'T be the first off the line
Coast a little
Loose weight in your right foot
USE cruise control as much as possible
Carry as little extra weight as possible (leave your anvil at home)
Make your tire pressure close to high normal
Don't fart when passengers are in the vehicle
