what to look for when buying a newer truck w/ ISX?

[ScarfaceTrucking]

buying a used truck is really crazy these days, with all the problems that pop up in these engines you JUST know the last owner tried to get rid of it because of an issue, then you have the fleet trade-ins which are trucks that were totally dogged and had super high maintenance intervals so the soot wrecked havoc on the engine.

honestly if i had the time i rather just buy an old beat fld and spend the money to make it good, but then you also got the government cracking down im pretty sure pre-2000 year trucks will be banned from the road soonish not worth the risk.

im thinking of just waiting until i find a kw or pete with a cracked block and get it super cheap and just start from 0 at least i know what i got.
