Hey Shrek,
Having done the Red Centre trip previously in a Pajero, I can recommend:
- ARB Sport lift kit (springs and shocks) with Polyairs
- AT tyres in LT construction. We had Mickey Thompson ATZ's for 70,000kms and never had a puncture. The Cooper ST Maxx has a 3 ply sidewall for a bit of extra strength, however for our new 4wd I am leaning towards the Bridgestone D697's.
- The Bushskinz bash plates are a great peace of mind item, although there is no knarly stuff we will be doing.
- We had a roof rack basket but hardly ever used it, there will be plenty of us around if you need a snatch so I don't think Max Trax will be necessary for this trip.
- if the funds allow I would invest in a Tyre Pressure Monitoring System ( TPMS) - again great peace of mind.
- I can highly recommend our rear storage set up. It allowed us to utilise the space underneath, then we had two plastic tubs that we used for spare shoes and the other for spare non perishable food, then above those we had a fridge on the left and more storage space on the right.
- A UHF will be a must and hopefully everyone will have the 80ch ones
ARB kit and fitting of Bushskinz: I recommend you speak to Danus at Adelaide Off Road (ARB Stepney)
Roof Rack: Sunshade Products on Main North Rd, Blair Athol
