Having been to the Cape 46 times since 1987, all I can say it is not that remote anymore, and there are plenty of people traveling up there. Now I haven't seen many people driving around the Cape at night, so if I were you, ditch the light bar and spotties and invest in some lockers, gonna be a damn sight more helpful. AT tyres will do more than what you need, Palm creek, your gonna be winching out of it unless your the first one through in the morning, and then thats not a guarantee, Cockatoo creek, well you will probably be winching into the creek, simply due to the amount of traffic using the tracks up there now, Logans and Nolans, keep your fuel tanks full, as they can be deep and a half empty fuel tank becomes a very good bouancy tank. Don't overload your vehicle, this is a comman mistake made by a lot of people, everything you need can be purchased on the Cape and your helping out the local businesses as well. A good major service before you leave, pack the hoses and belts they replace, these will be your spares. More importantly is take your time, adjust your tyre preassures accordingly and drive to conditions, its about $8000 to get your vehicle off the Cape if you have done any serious damage. Drive safe and play fair.
