I don't have any experiance with the vehicle as I'm not qualifyied it, or have driven in it much.
But from what I know....... It has 4x4 (obviously) and electric locking front and rear diffs, that take a few secs to kick, so your screwed when your already stuck. While I was overseas, I didn't see the vehicle very much outside of the main camp. We used the LAV's alot more. It's a run around more civilianised usage type vehicle. It's a good replacement for the ilitis for modernisation.
Wish I could tell you guys more about it
