x2 on 30 amp being easy. I closed my "mouse hole" entirely. Pulled out all the cord and cut it off with about 2 foot hanging out the hole.
Then I removed the plastic "cover" for the hole, and screwed on a piece of cut-down plastic cutting board, to make a square cover for the hole. In this new plastic cover, I drilled a 2" hole for a marine grade 30 amp twist-lock connector which I wired up to the cut off cable for the rig.
Now with the cut off power cord, I wired the female version of the 30 amp twist-lock.
It works great and took less than an hour to do. Amazon had the receptacle and the local hardware store had the female 30 amp end.
Can't see 50 amp being much more difficult, if you go with a marine style connector.
