Another factor that I just remembered, and yes this is important.
When the trailer was moved where it was my roof did suffer some damage (thankfully nothing major but some damage) the rood was "pushed" down by a tree branch, around where co-incidentally the light is not working from... Which is why I was thinking that most probably this set of lights runs in a circuit around the trailer, the good news in this is the way everything is done I might actually be able to snake a new wire with little "show" and fix it all, and frankly if thats all it takes I just need the correct "gauge" wire to run and do this job. Since the light near the bathroom/closet works I think I could probably etch the wire there and then redo the run to the first light, and if it then picks up and works I could regain my lighting.
Plan to fix the bed this year as well and purchase a new mattress for it, a nice think foam and cut it out myself if needed because right now, our bed is pretty lumpy hot and small for us and since we use it at a bed 24/7 and never fold it up I figure a more comfortable mattress wouldn't hurt.
Thanks for all the advice you guys provided! I do appreciate it btw.
