George,

Our Newell Coach is the "Winter Demo" it was designed for show and winter weather travel. Picture attached

Which is a gorgeous coach . . . .

The coach has a DD 6V92TA 6cyl 2 stroke pre DDEC fully mechanical engine

This caught my attention . . .  a TWO STROKE V-block diesel engine!  AND 100,000 MILES BETWEEN OIL CHANGES!!! 😮  I can't imagine the stress on the piston and crank pin bearings, especially when, in a motorcycle two stroke, these bearings get their lubrication from the air-fuel mix.  But the diesel 2T is different . . . QUITE DIFFERENT (piston & crank not exposed to incoming air charge). 

There's a wikipedia article on the engine https://en.wikipedia.org/wiki/Detroit_Diesel_Series_92  but not much on the 2T operation of it (I don't think this will pass today's EPA emission requirements),  and another article on 2T diesel in particular https://en.wikipedia.org/wiki/Two-stroke_diesel_engine  . . . Still, not much on the animation . . . unless you want to look at this MARINE engine with an 8 foot stroke - quite long, and quite different than the DD92, but similar concept and very well explained.  https://youtu.be/IM8rxp8qB8k?t=106

And *THAT* is how we spend our retirement!

Don’t need to change Oil as you are constantly adding it.

That engine was very popular in the trucking industry back in its day. Pretty Bullitt proof

Yeah we had a 6v92 and and 8V92 and both ran awesome. They were not called screaming Jimmie’s for a reason.
