Australia has the biggest truck combinations on the planet - "road trains" - they are the real "full size trucks".I'm sure it happens all the time, Australia isn't like Europe where roads are too small for full-size trucks. American 2500 and 3500 trucks are even marketed and sold there (RHD converted).
There are allowances for foreigners on holiday to use a LHD vehicle while in country but I'm not sure about specifics such as length of stay permitted.
Having driven a LHD vehicle in RHD traffic I would not recommend it. I would do a RHD for sure, I narrowly avoided a few accidents that were due to blind spots!
Do you think that there's not many F-150s/250s simply because their availability is limited, or because they're just not suited for the Australian off-road?Australia has the biggest truck combinations on the planet - "road trains" - they are the real "full size trucks".
Having said that, in terms of overlanding, as Paddler Ed says, you'll see F150s/250s but not that many. The vast majority of overland vehicles, in our experience, are LCs, Patrols, and Pajeros, along with Hiluxes, Rangers, and similar utes, and a few LRs.
re "allowances for foreigners on holiday to use a LHD vehicle" - as long as the vehicle is less than 3.5 t GVM you don't need to do anything. If more, then you need a "LHD" sign on the back. You'll be driving on a carnet, and there's no other paperwork requirement. The vehicle does need to meet Australian Design Rules (ADRs) in some respects. As long as the vehicle is legal in the country of registration you're OK, HOWEVER obvious things like "dangerous protrusions" are potentially going to result in problems. Although you'll see many vehicles with (for example) exposed winches, which can be considered "dangerous protrusions", it's a good idea to make sure that your vehicle is not going to attract unwelcome attention from the police. You can stay as long as the carnet is valid - 12 months, normally, with the possibility (depends on the country of registration) of a 12 month extension. If you are RESIDENT in Australia, then you have to register the vehicle, which is a different challenge.
Australia is one of the easiest countries in which to drive a LHD vehicle. There's hardly any traffic (which statement is always a surprise to Australians, however in absolute terms, the traffic is really light), and out of towns roads are usually straight and wide, so overtaking is easy/safe, certainly compared with driving a LHD vehicle in the UK (for example) or a RHD vehicle in Norway (for example).

Only ones that come out of Japan are the Land Cruiser and Patrol, everything else is from Thailand (Toyota Hilux & Fortuner, Ford Ranger, Nissan Navara, Isuzu DMax) or China (Great Wall, SAIC)Also Japan is a lot closer to Australia than Detroit and their vehicles are already RHD. So there's that too.
What would you say is their limiting factor and what other vehicles would you recommend instead?I think that they're not ideal for the Australian environment, AND that there are more suitable vehicles, which means that they haven't penetrated the market.
Short version - Size - too big (not a major issue in Australia however evidently you're planning on a trip including other continents as well and some places the size will be an issue); weight - too heavy, track - too wide (won;t fit existing tyre tracks - can hence scuff/wear, damage on tree stumps, use more fuel since you're breaking new ruts), engine - too big (fuel consumption is high - fuel is still more or less free in the USA... however in many parts of the world you won't want to pay for the quantity a big engine will require), availability of spares (depends on what you need, some stuff is available, but if you break something not available readily then getting it can be a big problem). familiarity of the vehicle to mechanics (finding someone who's knows how it's built, etc.).What would you say is their limiting factor and what other vehicles would you recommend instead?
