No Class A uses all Ford, Freightliner, etc parts for the dash. On my new E350 the entire HVAC, radio, dash switches, rear camera, ie everything in the dash is Thor stuff. Yes, Ford supplies power to some of it like my cigarette lighter outlets from a cable to the Ford fuse box. But other stuff like the radio/rear camera display is all Thor.
For example the radio/rear camera display is powered as best I can tell from a relay fuse box in a compartment underneath the driver's seat. Its incoming power comes from the Ford alternator/battery circuit but the relays are triggered by Thor circuits. So it is all a weird mish mash of Ford and Thor supplied power.
