I like the style of dimmer I linked above, so I rebuilt the switch panel near the entry step well on my Sunseeker to accommodate the switches I like. See photo. The dimmer is for the awning light, and the others are for the awning, porch light, and motion light.
Here is another thread asking the same question as in this thread: https://www.forestriverforums.com/fo...er-101604.html
If you don’t have the space on your panel for the same dimmer I used, there are other styles. If you type “dimmer” in the search field, there are many discussions about various 12 volt dimmer styles that work with LED lighting.
