The Toyota Landcruiser is easily the most popular offroad vehicle of choice in the outback of Australia for several reasons (and a couple of primary variations, eg. Check out the Toyota Troop Carrier on google) with a towing capacity over 7700lbs on its standard v8 Diesel engine and the ability to stay in one piece over the rough conditions our roads can get to (needs to be seen to be truly understood), makes it a really strong competitor in the AUS market.
Very simple interior, I think only one cup holder in the whole vehicle, power windows optional, air conditioning optional, floor mats optional; the local aboriginal communities out here use them for transporting family (seen 25 in a troop carrier that seats 10), hunting kangaroo/emu/whatever and they rarely stick to marked roads or trails, they get the }#% beaten out of them and they just keep going.
They are the primary vehicle of choice for bush communities, authorities, government workers, mining operations, cattle station operators.
