. . . I think you observation that the C-12 saw limited use in MH's they were very popular with in OTR applications with 750,000 to 1,200,000 miles between overhauls.
From searching for C12 fuel economy, etc., most of the discussions I found were about C12 engines in OTR trucks (seems really common in dump trucks) and in marine (boat) applications.
I didn't want to put too much stock in that, since I figure they're probably tuned differently than the C12s used in a motorhome.
But 8.5 mpg is a figure I could live with, and it seems like a rock solid reliable engine.
Thanks!
