Seeing that I've owned a Mitchell Motor Coach Vogue for about 11 years now, I can speak fairly confidently about them. Although mine is the Prima Vista 37' with a Cat engine. Mechanically, it has always been fantastic(knock on wood) and in the years I've owned it, I have replaced several house items....Refrig, air conditioners, tires, of course plus I've redone the TV's. That coach your looking at appears to have the original TV's installed particularly if the TV is still between the front seats, just as mine was.
Keep in mind these coaches sold for upwards of 300,000.00 when new and were considered a high end coach in their day. Featherlite bought the Vogue name after Mitchell and continued to build the Vogue coach for several years following 1996, but these were buiult of the Prevost chassis.
The one your looking at appears in Great shape still with a paint scheme close to mine(recently have had issues with clear coat peeling.) I would not worry about the "orphan" status at all...the components of the Vogue, both House and Chassis, were top of the line for there day and are all easily repaired/replaced/maintained. Good Luck with your choice. If you have any questions, feel free to message me.
