Melted plug prong - would you use it?

I was given this cord form a gentleman who sold his rig. I can't use it as our camper has the rat hole cord - however, I'd like to replace it with this type of setup (had the cord pretzel on itself twice already and had to remove storage box top to untangle). However, it looks like this thing got in a fight with a potentially bad pedestal. I can sand off and clean the oxidation, I have checked the continuity and everything seems fine. Our old camper had a similar issue and we didn't really have any problems. Should I use this and make the swap?
