In my two previous trailers, the lights were turned on at the light fixture. No wall switch. My new one has wall switches.

The cabinet wall on which the television wall plate is mounted is hollow and already does have wires running through it up to the ceiling area but easy access would require pulling that panel free in order to fish wires up into the ceiling. That wouldn't be difficult but I'd imagine that then fishing those wires across the interior of the ceiling to the vent area would be.

And that focuses on the challenge. However, some good news is that I already have run a fish tape above the ceiling over to the very top of that panel where it meets the ceiling. (If you remove the vent garnish you can see a truss running laterally across the ceiling/roof. And fortunately it does not interfere with getting to that hollow area behind that paneling.) But I don't know if there is access through the ceiling behind that panel above the hollow area.

My best skills are not in carpentry, and I don't want to damage any paneling or cabinetry in gaining access to that area. So I want to tread lightly there, especially since all of that stuff is understandably light weight and downright flimsy! Thoughts?
