Is this a good deal or not?

I'm not a mechanic but have read on here for quite sometime. I would say the miles are perfect as it has been DRIVEN! A diesel engine can go way, way, over 100,000 miles if maintained properly (the Allison too). Make sure and check the maintenance records and you might want to have an analysis done on the oil if it's not a fresh change.

Keep in mind that most likely all the appliances are original and will need replacing as time goes on, it is a 16 yr. old coach. Sounds like the microwave is newer with it being a convection/microwave.

Good luck and let us know what you decide,
MM.
