Being only used for about 2 years, I would not. It’s an orphaned engine, not easy to be rebuilt, and is not a fuel miser either. To me there are better choices out there. It may be good and maintained but here at work we have used them exestensively. They don’t hold up as well as the newer 6.7 engines. I think even the older 6.0 were better in some respects. Sorry that’s my take, never owned them just used them here at work. The one your looking at may be good, it it’s up to you. I have heard that parts are expensive on those engines, so something else to consider.
