I think the Kluger will amaze you where it can go. However with ALL AWD/4WD a little bit of common sense is always worth exploiting. The ground clearance is about 200mm which will see you over most rough stuff, however if not certain stop and have a look at the road area in question. The car does not have Low Gear range, while it will get up most respectable steep grades, if it has to climb over rocks an extremely steep inclines, it will fail. The tyres as already commented on, are road tyres, so do not expect miracles in mud. But crossing some slushy terrain will not be a problem. Also diff locks are not available so if you get one side of the car bogged (both left wheels or both right wheels) you will not be able to drive straight out. I took mine on a round Australia trip last year and got into the Bungle Bungles where the only challenges were 7 creek crossing with about 50cm of water which the Kluger did without any difficulties at all. We got into Palm Valley near Alice Springs without any difficulty at all. We also drove on a beach with average sand dunes and wheel ruts without a problems (by letting the tyre pressure down). We also toured many national parks were the tracks I would have graded from easy to challenging. Most people would be surprised were even a 2 wheel drive, let alone a AWD will go. I find that with a small amount of common sense the driver's limitation are surpassed before the vehicle's limitation. Enjoy your trip and do not worry to much about the Kluger's capabilities.
