My truck before the H2 was a 1996 Mitsubishi Montero SR (an OUTSTANDING truck until someone destroyed it in an auto accident). The Mitsu could go from 4 wheel drive (locked center & rear diff) to AWD to 2WD -- -- and the latter seemed to get better milage than AWD or 4WD.
I could be wrong about this, but that's what I remember. Someone straighten me out regarding whether the H2 would get better milage if it had 2WD.
BTW: I've had my H2 for more than a year and it has been PERFECT. Every switch, every fitting, everything.

Well, George, you got the misconception part right.
You are simply reducing the power flow through the front and nothing else. You are not disengaging any of the front drive since you you would also have to somehow add in locking and unlocking hubs to do that.
Mainly though, you can't draw a comparison between vehicles as the H2 simply will not achieve significant gains in gas mileage unless you first do something about the aero and the weight.
So, it gets back to common sense. What if you could get 2 mpg more by switching out T-cases and slapping in some manual hubs. How long is it going to take before you get back the costs of the conversion by saving only 2 MPG.
