Bought my first Prevost 3 yrs ago which I still have. Intentionally purchased a Featherlite because their systems are reasonably basic and are not proprietary. The earlier ones like I have are fairly basic on the electric side. Audio/video is old school with a lot of wires etc. Todays WiFi and Bluetooth will make changing/upgrading A/V system easier (haven't gotten that far yet). Slideouts don't have the air seal (it's a good thing and a bad thing) which makes the coach quieter.
