I would look in the mid 2000's for a gas coach since most made after 2004 will have decent engines and newer systems in the coach. Both the Ford and GM engined coaches from the mid 2000's should go 200,000 miles with normal maintenance and they are new enough that parts are available at most auto parts stores. Some of the GM powered coaches have an Allison transmission which is known to last a long time with minimal maintenance. Try to find a low mileage coach that was not used by a full-timer. This would have lower hours on the systems and less wear on the furnishings. If the electronics are already updated for TV reception, that is great.
