Looking at a used truck

[Scoot5869]

So I am currently in the market to replace my paccar motor truck with a Cummins powered rig.
I am currently looking at some 2018-2020 Kenworth t880 that have 500hp Cummins with 10sp and 3.70 rears and have the others specs I would require as well. Miles are anywhere from 230k-450k. What are some things that I should be aware of on these newer engines in that mileage range. As far as I know they have not been deleted. Are the fuel pumps on these motors to be replaced at that mileage still. I would also assume an egr tune up would be needed as well. If I pull the trigger on one I will probably run it stock unless the whole after treatment system needing an overhaul then I would take care of that. Thanks for any advice and help
