Hi Stan
If you are dead set on visiting the corner, buy a small tent or some swags, leave the van in
Birdsville and take your time and experience the Simpson in a relaxed state, and not stressed to the max wondering how the hell you are going to get there and if you can get back in one piece.
We are no strangers to the Simpson, having travelled in many, many times and I have been searching through my photos to try and give you an example of what the dunes are like and showing that it is not just an afternoon drive in the largest parallel
sand dune desert in the world, but will
test any first time visitor and learn how to drive over the dunes without cutting the hell out of them.
These are typical Simpson dunes and do not show their true extent of how cut up they can be.
This bike was fully loaded and was constantly bogging down.
This image shows some of the way the dune surface is cut up with usually soft sand. Then at the top of many dunes, you will not know if the track goes straight over, or at the last moment takes a sudden turn to either the left or right.
You can not take fast run up on the dune faces
This image will show you that the tracks are narrow, cut up dune face where speed will not get you over the dune, but low tyre pressures and experience. Sand speaking of experience, if by any chance you still went out there, what tyre pressures would you run?
If I to to in your vehicle, I would most likely by running around 8psi in your van and 10 to 12 psi in your tow vehicle. You might think these figures are a lot of bull, with trust me any higher that that and you will not 10 feet up a dune without bogging down.
No easy run over the countless mini small dunes
This image shows that the inter dune corridor is in many
places not just an simple drive. There are many mini small dunes that will slow you right down and then there is the larger and softer dune in the background to try and safely get over.
Another example of a dune approach
Look at the track leading to the top of the dune in the background. Cut up slow going and get your gearing wrong before going over the background dune, you will be stuck one again.
No flat easy drive
This dune shows that it is not flat going and the constant
rock and roll will damage your vehicle, tow bar and caravan. I say tow bar for a very good reason, from experience that I have see on the
Anne Beadell Highway.
Trouble on the Anne Beadell Highway
I told the owner of this converted to be made off road van he would not get through in one piece.
The end result on when he reached
Coober Pedy was nearly every side window broken from constant hard hits from very close vegetation, both side of the clearance lamps smashed, cracked chases on the van, but worst of all, a brand new tow bar cracked from the constant beating. Then to add to the trouble, the tongue bent with the constant un and down pressures. As we know, if you tried to bend one in a workshop, you would need an oxy and lots of very hard work, yet nature made easy work of it. The van was inspected at a workshop when they arrived in
Coober Pedy, Insurance Companies where involved and the end result the van was a right off.
Some swales are large.
This example of a large inter dune swale showing the dune that needs to be crossed and you can make out the change in direction near the top of the dune, which no way of a fast run up.
There can be many mini dunes to cross even before reaching the very far off big dune
There are many things in life that we would all love to do, but in reality sometimes it is just impossible, so if you are still sure that you can do it, the next question to answer is.....who is going to snatch you constantly over hundreds of dunes?
Some food for thought.
Cheers
Stephen

Another thing to keep in mind that ties in with Stephen's excellent post is that the max tow weight for a vehicle is usually drastically reduced in true off road conditions. Land Rover reduces the Defender's 3.5 tonne tow rating to 1500kg when off road. The extra stress on the vehicle is considerable.
