Thanks so much for that insight on your background, experience, etc.  What a crazy 5 months that sound ls like.  I think you’ll be very happy in any Newell that has been reasonably maintained.  Tons of redundancy is built into systems and between this group, your skill set and 24/7/365 factory support it’s hard to imagine any downside from my perspective.

The only thing I would research if you get into an ‘11 is I believe that is the year Newell went to a Cummins and some of those early years of that engine had a significant problem.  Sounds like most got resolved thanks to Cummins standing behind it, but not all.  Others with more knowledge than me can chime in on what the issue was and what the fix was.

Regarding the Cummins engine issues. The problem was nearly restricted to the 650's. They would drop a valve in #5 cyl.  Everything  went bad after that. Some of the warranty claims were north of $40k. The issues had to do with EGR and welded valve heads. Cummins was extremely lenient with the warranty claims on these, some of them being 9 yr old but 60k miles. I was personally involved in over 20 of these. All of the ones I was involved in were 650HP in diesel pushers. Never saw this is a 'deleted' engine though. I was not involved with the actual repairs other than to look at the invoice, butt I did witness first hand the actual destruction in  at least 5 units. About 1/2 were US coaches in western Canada. I have been out of the game since 2018, butt haven't heard of a catastrophic failure for some time mow.  A printout of the ECM history will tell a lot. Costs about $250. Its a deal. Good luck.

Thanks for this info.  I was told the current X15's are fully choaked down to the minimum HP.  Allison said no more 650HP as these were blowing up transmissions.
