In the Docking Bay
I have a 2014 29RE. The switch for my LED Cap Lights are in the area with the Docking Station.
There were some complaints in other replies, that the switch should be inside the control panel, inside the camper. I like having the switch on the driver side of the tow vehicle. It is more convenient if you are hooking-up/un-hooking after dark. After all, that is what I use them for the most, lighting the hitch area.
