Help

I just bought a camper.That's in desperate need of renovation.I don't have the manual.I suspect it is a nineteen eighty seven norman weekender nineteen foot travel trailer. I'm still trying to pull up specs and everything and i'm having a bear of a time. At this point I'm assuming I'm going to just have to rip all the electrical out and put new electrical in.But I'm trying to find out specs.On things where it's like I don't know what goes there whatever it was there's no longer there and my kind of need to know what it is.
