I've added 12v RGB LED strip lighting inside - on the top of the trim around the slide facing up... With a remote can be any color or brightness.
Any light switch can be replaced with a dimmer *IF* the bulbs are compatible... Not all LEDs are dimmable - so that may be a restriction.
If I recall - CW has a slide dimmer that looks like the normal RV switches.
Not yet retired...
