Mouse hole for power cord

[Deb Mac]

I’ve got a mouse hole, but a short cord inside with the long separate power cord. Not sure if some PO cut a 30A power cord short and wired it into the panel. But I can’t fit either plug through that hole, so I have to feed the cord through the opening in the bumper to plug in. Thinking of installing one of those 30A receptacles where the mouse hole is. https://www.amazon.ca/Power-Receptac...%2C223&sr=8-11. But that’s another project farther down the list. After the shower hose, and poor man’s Sealand and checking and adjusting the struts and shells.
