If I understand engine ratings correctly this is a 465 hp DD but not sure of that. This sounds like a big four stroke series 60 truck engine to me but I'm hoping someone will post who knows for sure.
A Newell is as good as you can have for a coach they were a little rough for a few years on finish work when the Amish in OK were doing his work but Karl has that problem in check now.Hey BK find a bus on the road using a 625 Hp Cat they are not under powered by no means,I have watched the units being built and was impressed with the construction of the 2000 P mode. one draw back to the Newell it has no resale but what high end coach does good luck
