Freightliner Cascadia w/ Detroit Diesel reliability/mpg?

Hey there,
I expect plenty here have experiences with this config. Late model (2015 and newer) Cascadia with the DD13 or DD15, general reliability, availability of parts at dealers and truckstops, ease of servicing, mpg in a variety of circumstances?

Mechanics and other drivers seem to like the DD15, and there are bazillions of used ones on the market because it's ex-fleet. My boss is thinkin' of getting one new or "gently" used with a few years on it.

 

because he's busy dealing with Brokers and trying to find a third driver. He doesn't actually drive, and after he made a mistake of buying a truck with a paccar engine I think he realized that the driver has a lot of insight he doesn't have.

He wants me to help him narrow down the engine/transmission combo, and make and model... then once we find a good trade-off between reliability and fuel efficiency and Driver Comfort, he can go to town on deciding whether to get new or used and whether to lease or Finance.

but I'm not complaining, it's something to do in my spare time when I get bored and why wouldn't I want input on the truck I'm going to be driving?

I like doing research....

 

I'm sure the boss is doing his own research. but obviously if he is suggesting I look into it for him... Maybe two heads are more likely to find something good then one?

I did use a search function but couldn't find anything on the latest models of Cascadia last good post seems to be from about four or five years ago.

 

Yeah the New Cascadia seems to be heavy on pushing aerodynamics quite literally down to the ground as far as they will go without scraping off the pavement...

I was looking at the Freightliner website something about using GPS height maps for predictive cruise control to squeeze out a few more precious drops of fuel. Integrated power train for whatever that's worth, the New Cascadia...

Honestly it seems like the technology has reached a peak if this is what they are relying on...

I drove a Volvo my first year oh, thank had def and src and dpf problems up the wazoo and so did all the other Volvos Eastern operated!

I imagine getting a Cummins in a Freightliner has its own issues.
