- can the air suspension really cope with thousands of miles of poor roads? Yes if the roads round here are anything to go by! Although a full health check before you go is advisable, double checking bushes and replace any that show the slightest sign of wear, front ball joints will take a hammering, they aren’t massively expensive, maybe replace them before you go?
- ditto the transmission Get the oil in the trans changed a month or so before you go, this will a. be a help in the heat and b. if any probs from the change occur they will do so before you go
- can the cooling system cope with the heat and dust? As long as it is in good condition then yes, if you suspect the coolant is old then change it, if you ever get any overheating currently then it will be worse out there, dust is a bigger problem for the air filter, take a spare or two
- are the electronics appropriately sealed from water and dust? Yes, to an extent - safe from water up to the wading depth and a little bit more, the seals on everything as long as intact should be fine for the dust.
- will I be able to get diesel of good enough quality? Not sure on this one, but a diesel is a lot more forgiving of poor quality fuel than a petrol
- what is going to potentially strand the car in the middle of nowhere and end the trip (eg: is EAS failure a disaster or can you continue slowly on the bump stops, if the gearbox throws a wobbly can you still maintain drive even if its only in one gear etc) gearbox failure will either end in limp home mode or no drive at all, engine failure same, EAS will just mean a bumpy ride but doesn’t actually leave you stranded
