Hi,
The suspension system is really top notch. Tracks really great on the road, and off road very stable as well. I haven't done much offroading... mostly just desert roads. I did the Mojave Road trip about a year ago which was a blast.
I never calculated the MPG I was getting, I know it wasn't great but it wasn't horrendous either. Honestly I took the head in the sand approach
Guess I could drive it around for a few days and calculate.
The tires don't rub on/offroad with one exception - if you turn really sharp while hitting a bump the tires rub a little and you get a traction-control beep letting you know.
I shot these pictures just the other day:
