Have a 2003 Fleetwood Bounder 35R on F53 Chassis. I have a mystery rocker switch on left drivers shelf, between the rear view mirror controller and the cup holder, Has a headlight logo on it but it is...
Could also be nothing hooked to it. My DP has 12 volt fans in the front and power sunshades. On a similar model that didn't come with those items, the switches were still there, but were hooked to nothing.
