* In fact, so heavy that with the metallurgy at the time, it would put so much stress on the remaining wheels that it couldn't cope.
Why do you say that? I said it's not because they couldn't. IFS continued at the time for even heavier armoured vehicles, Tatra continued with IFS at similar vehicle size to a Kat1. Excessive stress isn't stress that can't be built around, just they chose not to do that
Yeah, if people doing that project from 1965-75 thought independent suspension was too complex and not viable for a super heavy*, 10 wheel (or more), slow truck, then independent suspension must be inferior.
I take it all back. We should all use the same type of steel used 50 years ago and built cars the same way they built huge trucks back then. But why stop there? Why not drop the tubeless design of wheels and tyres and go with tubes? And why even that? Let's go with solid tyres instead of pneumatic tyres, because what they thought in 1839 (that it wasn't feasible to have pneumatic tyres) must still hold true today.
