Int the 2.402 PUMA motor actually a light truck motor and has Heavy Duty characteristics (cast iron ribbed block etc.) that make it more durable than say a regular Jap motor such as the D4D ?

The new Ford Ranger will have a 5cyl 3.2 l turbo diesel engine that will put out 460nm torque.......that would have been nice in the PUMA ?

All good and well, BUT:

A smaller engine must be more highly stressed to deliver the same output as a bigger engine. Inevitably, this means the 2.4 engine will not last very long - and by very long I mean compared to the Tdi engines out there that are still missioning up and down Africa in the 400-500,000km mark.

I doubt the Puma engine will last that long...

Oh I don't know, the PUMA has been de tuned to have only 90kw of power, and relatively low pressure on the common rail bar, 6000psi I have been told. It's married to good gear box so if looked after it will probably get there. On another hand if it were similar to Mitsubishi's current 2.5lt which has 131kw and runs 30 000psi at the rail I'd agree with you.
I think the long term issues for a puma common rail is fuel quality/purity.
But this is just mho.

I tend to agree. A few posts on here about fuel issues.
Would like to fit more/better(?) filtering but am very wary about warranty issues. But once the 3 years are up...

Indeed, that's why since Day 1 I have been adding 2-stroke oil to every tank.
