One thing that can happen with a power cord, especially if the plug is not of the molded type, is that water and other contaminates can enter the end of the wire and "Wick" up into the cord causing corrosion... I've seen it as much as a foot or more of corrosion on some wires I've checked.
I would cut back till you get good shiny copper and put on a new plug, seal it well using liquid electrical tape after assembly (You don't want that on the screws) and keep it clean and dry.
Many times motor coach power cords are left lying on the ground, the plug is plugged into an extension cord and left lying on the ground, it rains, a puddle forms and the plug (and the outlet end of the extension cord) are left under water. RV cords are not designed for this kind of abuse (Marine cords are, but a marine plug is over $100, and that is just the plug)
