Where is the cord arching, if it’s the male end or female end, they sell replacement plugs. Much cheaper.
I've replaced various cord ends over the years but never though about doing this. I hate the way that 50 amp cord pulls down on the twist-lock receptacle! I think I just found something to put on my Christmas list.
I had the same issue. I ended up buying a 2’ cord. The rv end was a 90 degree plug and the other end was straight and my cord just plugged into itI hate the way that 50 amp cord pulls down on the twist-lock receptacle! I think I just found something to put on my Christmas list.
You need to realize that burned blades on the RV power plug is something that happens from time to time and will happen no matter how well you maintain the RV. It can happen to a new plug if you connect to an outlet that is old & worn or burned by a bad plug belonging to a previous user. The replacement of power plugs is a relatively normal thing and if you are fulltime long enough it will happen again. Replacing the entire cord will not prevent that from happening again in the future. It is very easy to find quality replacement plugs that are watertight and which will serve just as well as one of those molded onto a power cord. Amazon has them as well as any good RV supply store.
I had a 30 amp to 50 amp twist lock adapter like you describe - this way if I was on a 30 amp site, I could use the lighter 30 amp cord. I also used it when plugged into my 30 amp at home. Rain ended up seeping into the connection and fried it. I replaced the female end of the 30 amp cord and decided to buy a 25' 30 amp to 50 amp twist lock cord instead of using the adapter.
Here is a pic of the solution that I've been using for the last 5 years. A piece of 1/4 cord, a bowline knot on one end, a slip knot on the other end.......simple solution, and it just works. The bowline end slips over the recept which is anchored to the wall of the RV. Once that's done, plug in the cord and adjust if needed so that the 1/4" rope cord is holding up the weight of the 6/4 Power cord. It takes the strain off of the plug/recept and the wires inside the power cord.I've replaced various cord ends over the years but never though about doing this.

He’s actually looking at this system. He doesn't like the price but is convinced it might be worth it.
Nothing that you do can prevent it from happening under any circumstances. Making sure that the power pedestal breaker is open before connecting is not only a good practice for the plug, but it is also a good practice for safety, and should always be done. It will help as well if you refuse any RV site where the outlet to plug into is in bad condition, weathered, or any signs of damage. A good outlet can be damaged when used by an RV with a plug that is in bad condition, and then the outlet will be damaged, and it will then arc to the pins of the next plug put into it and so start damage to it. But if an outlet looks new it is probably in reasonably good condition. If the outlet looks weathered, melted, or in any way shows previous damage, it probably is and will start damage to your power plug.
Which end of the cord, pedestal end, or RV end, you didn't say.
