Chris,
I haven't heard of Republic, but that doesn't mean anything negative. I would make sure I got all the converter manuals (in addition to the Prevost manuals) if at all possible. I assume you are aware that the 1992 has the 8V92 engine which is a 2 cycle engine that may burn a little more oil and smoke a little more than you are used to. They were fine engines but very different from the Series 60 that replaced it. Prevost started installing the Series 60 engine in the 1994-95 time frame.
