You're still not comparing apples to apples though.
I found 1 pic of a 70series with broken back.
The helper air bags kind of illustrates the point too.
The lesser Japanese utes can't match the carrying capacity of the 70 series without them.
There's plenty of pics where the break is away from the air bags
That's my point. There is evidence everywhere of bent ute chassis. Everyone knows it happens and why it happens. There isn't evidence anywhere of the claimed endemic IFS issues.
I found this interesting. Toyota Australia have raised the GVM on the 70 series to 3510kg. This puts them in a light truck category so it can meet simpler crash standards:
2023 Toyota LandCruiser 70 Series increases GVM and keeps V8, for now
New load capacity increases have been confirmed for the 2023 Toyota LandCruiser 70 Series, along with its turbo-diesel V8.

Before the GVM was around 3200-3300kg depending on spec. No different to much lighter utes. Big problem in countries where police weigh light vehicles.
