is that possible or is it too heavy and bulky?

Oodnadatta and Birdsville can be done in car.

Hi Heiner
It all depends on where you want to go. Certainly the French Line would be almost impossible with such a vehicle as it is too low and with the state of the track you are more than likely going to bend the chasis. However, many dirt roads such as the Oodnatta and Birdsville tracks can be done with care. The issue is always going to be tyre suitability and whether you are prepared to adjust tyre pressure to suit. Of course this requires you need to carry a compressor. Other roads that could be done, again with care, would be the Gibb River Road, Tanami Road, The Great Central Road, The Cape Leveque Road and the PDR to Cape York. Anything that is generally unformed such as the roads across the Simpson Desert, the Anne Beadell Road, The Mitchell Plateau Road and the Canning Stock Route would not be suitable for this vehicle. The most appropriate vehicle would possibly be a Toyota Landcruiser with a camperbody. Extremely capable on the most challenging tracks.
Again much will depend on your skills not to over stress the vehicle. Remember also that mobile phone service in the Outback is sporadic so a satellite phone is very worthwhile. Enjoy your trip.

The hilux or similar in 4 wheel drive , I’m sure would do the hard tracks as well.
The photo, i presume is 2 wheel drive?
Cheers

It’s actually a pretty capable vehicle (we have an ex-hire one) and although we haven’t attempted a desert crossing and don’t plan to we found that the Plenty Hwy, Palm Valley, Boggy Hole Track etc are well within its capabilities. We bottomed out on some rocky crossings but have since added a moderate lift and a long range tank. You are likely to be close to your GVM so don’t plan on adding too much in the way of heavy extras like winches. I don’t think that chassis bending is likely as it’s single cab with good weight distribution, unlike the dual cabs. It is extraordinarily quick to set up and pack away and you will be hard pressed to find a better travel option around the $30,000 mark.

The pic 'looks' like its the 2wd version of the supposedly unbreakable 'hilux' ?? If its the 4x4 a 1/2 decent quality lift + a slight tire size increase with good A/Ts , and being very very WARY of weight and you can go any where , yes even the French line BUT you need to 'pick' your timing , not the 1st of the 'season' and not the 'last' as by now [Sept] the tracks are very very cut up ... the most important aspect is to 'have fun' and enjoy the trip ....our indigenous brothers still drive all the other track/ roads you mentioned in 2wd holden DunnyDoors ...

I've given uo this idea...
Why?
As the other members has already written it and:

Only small 75 ltr. Diesel tank.
Installing winch only with problems (new front / bullbar ?!)
No 2 Sparetyres ..
Clearance.

The car is probably not suitable for my trip.

Thx. for your comments !!!
