I recently completed a round trip with my wife that included two crossings of the Simpson Desert, partly solo and partly with another couple in a Defender.
Overall the trip was amazing and I’m very happy to say virtually incident free for the D4. Some of the details may be of interest to other D3/D4 owners.

Fuel economy
96L for 628km Birdsville to Jervois Station via QAA and Hay River Track
99L for 603km Mt Dare to Birdsville via French/Rig/WAA/Knolls/Poeppel/QAA
Both legs included a couple of runs up Big Red. The west-east route involved more dune crossing in comparison hence the increased fuel consumption but I was still pretty impressed with 16.4L/100km. The hardest sections of dunes saw up to 22L/100 for short periods but mostly the dune crossing was around 20L/100. The Defender we travelled with for the return crossing used around 105L.
Setup
There was a few changes compared to any other trip due to the extra fuel and water required, including temporary removal of the 3rd row and 2nd row seats, which reduced weight by 115kg.
I took the Drifta rear drawer & fridge slide unit I already had and made a ply platform for the second row space.
Third row space under the drawers stored most of the tools and spares while under the second row platform stored the main water bladder, air compressor and a few things that didn’t fit in the rear drawers. We slept in Oztent Bunkers that were stowed on the second row platform. The self-inflating mattresses, sleeping bags and ground mats went on top of the drawers in the back behind a Trav-all cargo barrier.

For fuel I carried 4 jerry cans; two on the rear wheel carrier and two equivalent (4x10L) on the roof rack.
If I was doing a similar trip again I would only take three jerry cans.
For water I carried 55L bladder under the platform and 2x20L bags plus a 10L plastic container for in camp.
If I was doing a similar trip again (& also in winter) I would leave one of the 20L water bags out and replace the 10L container with a 5L one.
The hitch-mounted rear wheel carrier worked out really well, kept the second spare off the roof and carried half the extra fuel.
It was rock solid even after all the corrugated roads and bouncing around over dunes.

This arrangement meant the roof rack was relatively lightly loaded with 4x10L jerry cans, 4 MaxTraxs, the awning and a small bag.
Using 10L jerrys on the roof also helps keep the centre-of-gravity lower compared to standard ones, as well as being much easier to deal with lifting on & off the roof.

Tyres - The 265/60/R18 KO2s were about 30% worn so went with them. Handled everything well but one slow leak was sustained coming into Birdsville at the start of the trip from a tiny but very sharp shard of rock that embedded into a tread block and caused a small hole that slow-leaked overnight. Once found it was easily fixed with a vulcanised patch for $45 at the roadhouse (fast, friendly and reasonable price too). The dune areas of the desert are not too hard on tyres but the approaches are savage; gibber plains, stony sections, etc.

I applied the protective film "Paint Shield" before leaving and was very glad to have it.
The amount of unavoidable extremely harsh scratchy bushes and spinifex was huge especially on the less used tracks we took.
Nothing got through to the paint. Detailed thread here:

Driving technique
Generally the D4 handled the conditions easily, only requiring a second attempt a couple of times when I didn’t quite carry enough momentum. Low range without any terrain response mode seemed to be the most effective way to maintain smooth progress. Manual shifting to third or fourth at the base of medium to large dunes worked well except for those so churned up with wombat holes that second was required. For all dunes the main criteria was to go as slow as possible to keep pitching and rocking to a minimum but this was not really an issue on the less used tracks like WAA. Tyre pressure was reduced once into the softer sand and I found 18/22psi worked well.
Llams was fantastic in many places such as the Chambers Pillar Track, Old Andado Track and heading south from Mt Dare. For the dunes I settled on factory offroad height because speed virtually never got above 35kph but there was a few sections with widely spaced dunes where Llams medium was ideal. I did get an orange suspension error that self-cleared just with an ignition cycle. It was algorithm based and I think occurred because I was using Llams at the time and the articulation was going out of sensor range or varying too often for normal height mode. It was a scenario in which Llams was unnecessary anyway.

This time Big Red presented no trouble, I dropped to 15psi and drove straight up. It was more difficult when I was there two years ago.

Accessories I already had for trips and touring:
18” wheels
Llams
rear drawer unit with fridge slide
dual battery
roof rack
uhf
tailgate lighting

It was a brilliant trip and the D4 was a fantastic way to do it.
Cheers,
