I had that combo on my first Foretravel. It is a good set up. The exhaust manifold on the older 8.3 is one piece and will crack sometimes. I replaced mine on my 99 and they made a two piece and no more stretching and shrinking issues. I think of all my coaches that 99 was the most bullet proof. Go to foreforums.com and register there. There are plenty of people still buying them and using them and upgrading too . I have seen 91s that are being updated even. No big thing to say other then see if it has trans synd in the allusion. If not put it in. 80 k is just getting broken in. I have 155k on this unit and have friends with 276 and higher on their coaches. Send me a pm and give me the details on the coach and maybe I know it if not I bet someone on the forum does.
