Multiple sales guys claiming their 12-14 CARB engines won't need rebuild until >600k

Scoping out trucks, feeling out salesmen; they're doing their salesmen thing "yeah we've got a great selection of used trucks." Oh I'm sure you do, desk jockey. "Yeah most of em are between 200-600,000 ranging from 40-80k" yeah but I was wanting to swing closer to 100k and not have to worry about inframe or any moderate/severe issues for atleast a few years...or just plainly go brand new "No, no, nope! 500k inframe is old school thought, these newer engines don't require a rebuild until well over 500k, made with tighter tolerances."

I've had probably 7 conversations along those lines, over the past few days about these newer CARB emissions standard engines. All of them lead up to the salesmen claiming an engine from either ; Detroit, Mack, Cummins or Paccar that's in the 12-14' range will not require any form of rebuild until over 600,000 maybe more.

well that's a grand thing. Probably not true but a grand ideal nonetheless, I mean how else would you try to sell a steaming hunk of crap?

I wanted to get some of your opinions, but the funny thing is...if you have an engine...made between 12-14', it's pretty unlikely to be at such a mileage range, yet. So this is a claim you can't backup unless we are talking about a team operated truck.

But wouldn't it be nice to have some conversation regarding this topic?


btw, in this order;

-Detroit and Mack are neck and neck for my business. Have had both, liked both, in high mileage range on both and they ran great, easy to source parts on and easier than others for myself to diagnose and work on.

-Cummins is distant second, don't particularly enjoy eating an EGR cooler but there you have it. Pricey to fix too.

-Paccar, have had the MX, was a nightmare but I'm hearing a lot good about it, willing to give it a second chance and thinking I might've got a rough stick end.

-CAT & Maxxforce completely off the table.


Thoughts?



Edit, worth mentioning none of these sales guys would put down even close to a guesstimate on what mileage, by they were him-hawwing around 750-800k+ Especially the DD guy.

 

Yeah I've got a DD 15 right now and it gives me zero problems. Check the oil level every chance I get, minimally every 2 days pop the hood.
My only complaint is that the EGR intake return has some soot blowing out of the side of the that high temp rubber gasket about 10 inches down the return unit.

washes off and it's as tight as can be on there so I'm hardly worried.

 

Thinking fitz Coronado 12.7, seeing a lot of em coming around with 1-200k miles for under 90k.
Anyone know why they're getting kicked back out? Hearing mixed reviews on these recons coming out the past few years. You know it's getting interesting when Rutherford is mulling over using recon e-7's

But also to see a truck msrp at 145k brand new, pickup 12-24 months or 1-200k miles then immediatly drop 50k in value is somewhat...interesting? But on the other hand, it is an FLD product...

 

I really see no problems with a CARB engine, yes there is the additional mechanical issues but outside of that they have hugely reduced pollution in our particular industry. I'm no Eco-nut but we as a species need to stop poisoning our planet.


Another discussing for another time, leave the government out of this thread- thanks much guys.
