What's the difference between the m1114 and m1123?

[Hummer Guy]

So, I know the difference with these is the half shafts, suspension, turbo, cooler, and AC but what else is different between the two? Is the chassis built stronger on the m1114s? Is there any other difference minus the armor?

M1123 is a third generation HMMWV, and the M1114 is an ECV so that makes it 4th generation.

The roof setup is apparently unique to those trucks as well (it's wider I think?)

I’ll bite.
the m1114 is a slantback. It has a larger cooling stack. I think it has a dexron cooled rear diff. It has an almost flatmetal battery cover. Other models have fiberglass. The commander seat setup is different.
