Any issues with '15 Prostar Cummins?

I need to replace my 725k mile Volvo, it's starting to get expensive, lots of little issues like front and rear wiring harness, etc. I haul fuel.
So, I'm looking for a lower mileage truck to replace it, with the consideration of resale in 2 years when I plan to retire. I found a 2015 ProStar with ISX Cummins, 13speed. 355k miles, for a good price. I drove an IH rental for a couple months a few years ago, and liked it, but not sure about any issues. I'm not a huge fan of all the things they hang on the outside of the frame under the hood, but is that really an issue?
Would love a 'Pete or KW, but not at those prices, especially since they all seem to have electrical problems. Company fleet is 'Pete and a buddy has a KW, they seem to be in the shop pretty regular for electrical gremlins. The Volvo has been pretty reliable until recently.
I do have both IH and Volvo/Mack dealer local, 'Pete moved out, nothing else within 75 miles.
