Hi Admiral (Keith), the only requirement the local police made at Halls Creek was to have a second spare wheel. Recommendation was an Extended 4WD. It was the rental company specifying no insurance on our brand new 4WD Toyota Adventure camper that did it for me. Didn't fancy coughing up the full price if it was totalled. Also, the recovery charge of $1,000 per axle (not sure of the distance, per 100km?), not too bad for us, but I suppose the cost of getting a roadtrain recovered adds up! On top of that is the personal damage part, that was my wife's main reason for deciding against. However, we did manage a stretch of 110km off road. My teeth have only just recovered from their shaking! It took nearly four hours to complete it, great fun! I wish I'd been driving a Range Rover (sorry Trainrider06). You can drive them 50mph across a ploughed field. I've owned two during my driving career, great but thirsty when gas costs over £1 a litre (when I was in the UK) £100 per tank, OUCH!. I also had a Discovery for a couple of years, it was new so didn't have any problems with it. Driving a Suzuki Grand Vitara now, seems to be going very well. Our second of the make, my wife loves it.
Bye now, men's Tennis final today (Wawrinka, Switzerland's last hope). Canadian GP later, perfect day to come.
