There will be dents in a car, that is for sure, have you seen how they drive in there? It works quite well, but one have to really learn to use horn and listen to horns of others, just don't turn towards horn, move when others move, stop when others stop, that should be enough to stay alive, oh and forget all rules, specially don't ever hit brakes if there is someone closing in from left or right, they will go past either front or rear, but if you brake one behind you will hit you and you may get fines from such move, it is like driving along bunch of fishes, they move like one.
Right of way is those who drive bigger vehicle and whom have waited longer, also if there is hill usually those coming from hill have right of way too, mostly because their brakes are almost non existing
It will be a trip that you remember a life time, I have been wanting to do something similar, but time or finance have been against that so far, maybe someday. With diesel it will be cheaper and also bit more relaxing because of high torque, but at least I need earplugs with my 240 diesel, it is not very quiet one and especially at long term noise is very tiring, much more fresh after trip when using earplugs.
Land Cruiser is perhaps best in comfort, but it is not very nice to drive on road, wind etc. affects it quite a bit, also it consumes bit of fuel, even when you use 2H, that is what I remember from it, even it is quite long time since I did drove with one, so my memory about it can be bit fainted...
edit: 240 diesel had mechanical injection like all old diesels, when you get thing started you will only need 9V battery to keep it running that is for shutoff solenoid, when it goes below 9V that thing stops running, but it does not need much of work, only thing is that motor itself is bit sensitive to operation of it, you need to make sure not put pedal all the way down until motor is really well warmed and you need to idle it 2 minutes before switching off, otherwise it can crack a head, that is one thing to keep in mind if you plan to get one used. I have driven over 1000km daytrips with my 240 diesel, only problem was when alternator failed (never serviced), but I still drove over 200km to home with failed alternator at dark autumn night. Thermostat could have been replaced as extended perioids of time doing 130 (kph) it started to heat quite a bit, also thing is very slow compared to 360, over 20 seconds to 0-100 (kph) it has only 140Nm of torque (or something like that) so at steep hills often needed to shift down and still needed to floor it to keep speed decreasing too rapidly. Good thing is that you can run even with veggie oil if no diesel is available.
I replaced some joints and one bearing from driveline, some brake calipers, exhaust and that alternator for ~100 000km which I drove with it, changed oils at 5000-6000km intervals as it started loosing them really fast if I kept them longer, might been bad oil brand too, it takes around 7 litres of oil with filter.
One tip, don't get one that has noisy heater fan, it takes two days to replace and overall it is really shitty job, some professional mechanics refuse to do it.
Timing belt need replacing every 100 000km waterpump replacing as often, so make sure those are done properly. Fuel pump belt is similar to timing belt, but can't remember how often it is needed to replace.
