Default Advice needed: How good OR bad is the 7.8L I-6 Isuzu motor?

Hi guys, I'm new here and am looking for some Duramax/Isuzu diesel engine advice. I only have experience with a few Powerstrokes, 3 DT466's, and a small CAT and small John Deere diesel.

Advice needed: How good OR bad is the 7.8L I-6 Isuzu motor?
I have the opportunity to get what is supposedly a good running 1998 0r 2000 Isuzu NRR T6500 cabover with an Isuzu I-6 7.8L diesel engine in it. I am in the tree business and want to put a 14' chip box heavy dump body on it and haul a big chipper with it! I can get the truck for a good price, but it does have 220k miles on it. How good or bad or reliable or unreliable is this motor?
I am ALL ABOUT preventative maintenance, so I change oil and fuel filters all the time, but I do not want to be replacing an engine in this thing!
Anyone have much experience with these motors or know much about these motors? I believe it is a Duramax/Isuzu 6H I-6 7.8L, but thats all I know. Is it strong, reliable, and long lasting, will it go the long haul? And how does it compare to the CAT motors that they also put in these trucks?
Thank you for ANY advice at all.

Ben, in Boston

Since this forum is for Isuzu cars and SUVs , I doubt you'll get an answer.
You might want to see if you can find a forum for larger, commercial trucks.
