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.
