As another 8V92 owner I agree generally with what you say. My comments, though, would be somewhat more positive. The air compressor hose failure issue is a definite reality, and I did not rest easy until I had them changed. The point, though, is that I had them changed. While it is true that many diesel mechanics do not know much about 2-strokes, there remain many who do. Inquiries in the forums can usually turn up a good recommendation in any extended area. I've used several, including 8V92 Wanderlodge owner Clyde Schumann at Seguin Diesel in Texas.
The series 60 is a great engine, but so is the 8V92. Detroit didn't stop making the 2-strokes because they wanted to - they simply had to because there was no way to bring them into compliance with changing emission rules.
I know there are some 8V92 owners who get 6MPG, but mine at 5.3 is more typical.
