Question regarding changing my shore power hookup???

You want a 50 amp 4-wire shore power inlet. The 4-wire is important, as there's also a 50 amp 3-wire, which is one less wire than you'll need. (Safety Ground, Neutral, L1 and L2)

Here's a few options for inlets:

Marinco 50 amp

And the mating female plug:

My 2016 Cougar 5th wheel has the power cable that pushes into the wall. Last trip out, 3rd park, I only had about 19' of 30' available. All bound up inside the wall.I just pulled everything out, unwrapped it all and resealed...
Thinking of talking to an electrician friend and redoing to the removable shore power. Really worried about it happening again... Sure many have had this done.
What do you actually call all the parts so I can do a search?
Thank you...

Sorry, thought later I should have stated the amps... It is 50 amp.

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.

Is it a 30 or 50 amp?
30 amp is easy! What I did was bought a short male cable (18-24 inch). Removed the old long cable and disconnected from junction box. Spliced near short cable to rig's interior wiring.
Purchsed a female 30 amp RV cord body. connected it to the old shore power cable making it an extension cord.
