My current dilemma is selection of vehicle. We will not be travelling in a hurry - am budgeting about 5 days for the Tanami 1000km leg, within an overall Broome - Adelaide adventure. 5 days for us two is about 250 cans of Bundy, which we like to drink ice cold. This impacts greatly on vehicles.
You want a vehicle that is easy to repair with easy access to parts. That means more or less a Toyota + 4WD + diesel. Troopy or a LC70. Troopy better as it has a 180L fuel tank (Most other LC70 like other toyotas are 130L). But there is a downside in putting all your fuel in one or two tanks.
Diff locks
Tyres should not be those low profile ones. 16in rims preferred. Carry min 2 spare tyres. I took 2 spare rims with tyres on them plus a 3rd spare tyre
Need to lower tyre pressures. I did 25 and when corrugations were bad 20.
Other spares/stuff:
Air compressor, tyre pressure gauge, fuel filters, engine air filters, cabin air filters, extra engine oil
I mounted a 3rd battery in my toyota.
The standard jack that comes with the vehicle is likely to be useless.
Snatch straps.
Satphone hire
Spare nuts and bolts for the chassis and suspension
Range Rovers with air suspension should be left in a capital city
While its 1000km i believe its sealed/gravel between Yuendumu and tilmouth
I think the longest stretch between fuel is 600km - (Balgo to Yuendumu). Which means jerry cans.
Note Balgo is about 40km off the Tanami (turn off at the pink car wreck) but fuel is usually cheaper than Billiluna
Fuel at Halls Creek, Balgo, Yuendumu, Tilmouth, ASP
However some try to carry enough fuel to traverse Halls Creek to Tilmouth which is about 800km. I reckon about minimum 2 jerry cans of diesel extra.
Low Speed + permanent 4x4 + extra payload + lower tyre pressures means fuel consumption goes up markedly.
Pretty sure permits are not required to traverse Tanami but might be required for certain spots along the way.
Note Yuendumu and i think Balgo is Alcohol free - as in drinking alcoholic beverages is not allowed.
UHF radio - channel 40 usually.
I reckon the best vegetable other than the underground ones on a 4x4 outback trek is cabbage. They survive being bashed around.
Edit Last time I was there there were no psycho serial killers at Wolfe Creek
Sorry prob info you already know.
