Assuming you are taking about the Male end that goes in to the campground plug
I would probably replace it myself if i had any camping in the immediate future
If waiting is no object , send it in
This is no more than the normal wear you would get on the Male plug of your shore cord using the same CG pedistel outlets, lots of whom have arcing and wear from users who plug in with A/C etc turned on when they should be turned off for connecting and disconnecting
We have thousands of members, but there are millions using these campgrounds with no knowledge or regard of proper procedures
