This is a common problem because the female portion of the pedestal gets really loose, from everyone plugging and unplugging. You can get a loose connection, which produces that heat. Always check when you're plugging in that your plug feels tight and not loose. If it's only slightly melted, it might be OK. You can order replacement Camco plugs on Amazon.
Some people carry a 50 amp to 30 amp dogbone, to plug into the 50 amp outlet, which is usually in better condition, and not used as heavy.
