Winch really isn't on my radar, and I think even if I do it it would be an external only thing. Good thought for sure though, totally skipped my mine.

Locker, I have QD2 so no need

Interter, I have an 800 watt unit with 2 plugs, that I plan to route to different locations, I'll be using a relay so that it only has power when the ignition is on, so the switch is more for cosmetics/not having to hear the fan if I don't need it.
