After being away from construction on my RV for nearly two years I've re-evaluated the wiring in the wings. Much to my dismay, I decided I didn't protect the wires frrom chafing and didn't clamp them properly. I don't know what I was thinking back then. I guess I was in too much of a hurry to get this done. I'm glad I didn't button up the wings.
