New leftover

I’m currently looking at buying a truck and found a new leftover 2020 389 at a good price. Does anyone know of any potential problems to watch for, I’ve heard about the DEF “crystallizing” if it sets around a lot but I’ve never ran anything that new and know nothing about what to look for. Other than that the truck is set up the way I want other than 22.5s instead of 24.5s but I was going to ask them about changing them.

 

Engine is a Cummins efficiency 525/1850
I think it will be enough power and torque but I will be hauling logs in the mountains of WV.

Everyone here runs tall 24.5s but there running straight trucks with pup trailers, I’m going to try a short truck and trailer. I guess the tall 22.5 would be ok but I’d prefer the tall 24.5s.

 

I’ll be hauling logs so I’ll be off road some, the rear gears are 3.91

 

That’s great to hear. I was going back and forth between kw and international hx that’s the only 2 dealerships near me then I found this leftover 2020 Pete that was spec the way I wanted and at a good price so I figured if something went wrong at least the resale would be high and the kw shop will honor the paccar warranty.
