Replaced the cursed 30A cord fine-thread locking ring!

I don’t use it either.  I plug the cord into the trailer, turn it and call it good.  I’ve never had any issues with water, connectivity, etc.  I also leave slack in the power cord to eliminate anyone from tugging on it.

Heck, I don't even turn it. I live life on the edge.

👍🏻😂

A bit of candle wax around the threads worked like a charm!

@YanniLazarus- It also didn't require a trip to the bank to get more money!

Thank you, @ChanW & @Tampakayaker, for the great tip.  Heating the yellow part of the old plug with a hair drier for a couple minutes worked great to soften it enough to exchange the rings.  It works great from the very first try & will save a lot of time & frustration for us. 
Adding this as #85 on my list of mods, and it may be the easiest one yet, and with the highest reward:effort ratio.

Thank you all for sharing this simple but effective mod.  Finally did it on my T@B.  I rarely camp with shore power, but use it at home to get the refrigerator cooled down before trips.  That locking ring was bear to tighten.   

Good to know.  I have yet to succeed with the default ring (my son has, though).
