In general terms, LC200 and LX are different trims of the same vehicle.
GX 460 is a trim of the LC150.
The 4Runner is a derivative of the LC150 platform. All components in the 4Runner are shared with some version of the LC150 other than the body and body specific interior parts.
Many components are shared among the various products in different markets. For example there are markets where the LC200 is sold with the 1GR engine we have in our 4Runner. In the USA, each model only is offered with a single engine option.
4Runner = v6
GX = 4.6L v8
LX/LC200 = 5.7L V8

There are kits out there to replace the air suspension with conventional shocks. Very popular for some reason with the off roaders

The GX is easy to swap.
The LX doesn't use air suspension. It uses a complex hydraulic pressure system combined with about a dozen expansion reservoirs and some coil springs included. The result is varied ride height, but also variable spring rates and variable shock compression and rebound rates that can all be varied in any combination - and also works in multiple channels, so the left rear may have a different spring rate than the right front.
In some ways I think the LX is a dream system. What it does that air springs cannot is lower spring rates and increase ride height at the same time. Air springs are the opposite. So at high ride height in any air suspension system without a negative air spring the suspension spring rates are also higher. So the higher you go - the less suspension travel you get. (I'm not aware of any OEM product with negative air springs). With a system like the LX you can have an on-demand higher ride height and also have higher suspension flex.
This is a great system in theory. The fear is the reliability and cost of repair due to how complex it is and how expensive each component is. My understanding is that removal of the AHC system in the LX570 is not easy to remove/disable without electronic problems resulting from doing that where the GX is pretty straightforward to do.

It is worth mentioning that the AHC diagram doesn't show it, but the system has coil springs that take up some of the load on each corner. So it's still far more reliable for remote travel than an air system. If the AHC fails - you only end up at the low setting IIRC. So you can still drive it, but it'll be at a low height. It won't be like a blown air system on a Land Rover or GX.

I think this an example of technological and engineering beauty. Since its made by Toyota I bet its very reliable. I hope they continue this level of work in the next generation.

If Trump tried to fix that he'd be getting sued by every blue state out there, just like they've been doing to try and stop him from lowering the ridiculously high 2025 CAFE standards put in place by Obama.

At the point it doesn't really matter anyway. ICEs are all gone in a few years anyway. And that's okay with me. I like clean air.

That's not at all true.

We'll see. All Toyota's will be hybrid or BEV by 2025. I'd bet all or nearly all will be BEV by 2035. And entirely all will be evs by 2045.

We'll need a new power grid first. The one we have can barely handle the present demand, never mind what happens when the entire country is plugging their cars in every night!

Peak vs average. Two very different things. We need more generation, but not as much as you might think. And it'll be cheaper than gas.
It's coming. Whether we like it or not. It's still happening.

It will be daytime charging that may stress the grid if not upgraded. The majority of users will charge at night, which the grid will handle better.
The other issue, as with most resources on Earth, are the limited materials. If all cars produced go Electric, the demand for lithium will dry up Earth's resources in about 15 years.
Oil will become very limited too, but not for a much longer period.
Hydrogen, which Toyota invested a lot in, has not received enough support. 10 to 1 power to weight ratio over lithium. Recharges faster than filling a gas tank. Hydrogen also has 3x more energy than gas per pound. It would require a lot more filling stations, but so will electric.
I think Hydrogen will eventually take off as the most viable solution.
At the same time, ICE engines will have infrastructure that no other tech will have for a long time. Oil has strong lobbying groups too.
I like gas for its flexibility, range of operating temps (good luck starting a hydrogen car at 0 degrees F), and availability. I know gas isn't the future, but it still makes thr most sense for the present.
I want new cars to go non-gas as fast as possible. It will leave me more gas to burn in my old Toyota rigs.
Agreed - Sadly most failure is because owners don't change the fluid in the system. Manual states to change every 60k miles.

How much does a fluid flush cost?

Hydrogen sounds like a perfect motor fuel. What’s the technology to mass produce it?

There are a number of ways to produce it. Biomass, natural gas or separated from water using electricity. It can be generated from water on site or trucked in. You fill your tank at a pump just like a gas station. I believe air travel will migrate to it as well.
The cost to add stations and production networks is high, but the oil companies could build a monopoly making and selling it along gasoline. It has to be filled at high pressure, so you won't be able to bring Jerry cans along. ICE will still be around a good while.
It is quite versatile except for cold starts.
