Stay away from anything with excessive mileage(over 300k) Colo. doesn't use salt so rust appears to be a non issue on Colo. buses. DT466/Allison MD3060 is what I have and is a desired combo.

I'd take a 5.9 Cummins over a 444E. But yeah the 545 is definitely a drag on the highways.
I'd avoid anything newer than 04'.
Hard to beat a DT466 or Cummins 8.3.
Buying a bus in CO isn't a guarantee of getting a high HP engine or a beefy transmission. I got a shorty from Aurora and it had a 175hp 444E with a 545. Also had nice highway gears in the rear @ 4.10 .
If you do get a real mountain bus from CO it will also very likely have a driveline retarder which is great.
