Replacing a 30 amp male plug on Class C umbilical cord

The molded 30 amp plug on my umbilical cord is pulling away from the cord. Tried pushing it back but to no avail.

Should I replace the plug or the whole umbilical cord and plug? The cord goes into my rig and disappears behind the refrig so whole cord replacement could get complicated.

Is it easy to just replace the plug? If so, any recommendations on a brand or style of plug? Do not want to cut any corners with a cheapo plug that is not weatherproof or durable. The original one has done well for the past 15 years.

Thanks for any and all suggestions and tips.

    Try again. On a hot day lay the cord out full length in the sun for an hour. Then start by the RV and work your way toward the plug using a sliding grip to work the outer casing out to the plug. Use some adhesive at the plug to hold it in place. I used JB Weld.

    Otherwise get the Camco or Marinco with a grip handle. Although these don't always fit in the mouse hole. Progressive Industries has a plain plug end. I would not trust the stuff I see at the hardware store.

    Sadly there seems to be no more quality plug than the standard Camco item many RV places sell. I held out for a Marinco (hoping it was better) but its quality was no better.
    Maybe someone else knows of a better make.
