I updated my travel trailer with 50 amp service to the Smartplug system about a month ago. One of the best Mods I have done. The change over adding the new socket to the RV, and the new connector to the power cord was simple and didn’t take very long. It has a much more solid connection than the old twist lock and is very weather resistant. What prompted me to make the change was a cracked twist ring that would not get tight enough to secure the plug in the socket and as a result was getting hot when using high amperage.
I agree without the locking ring the twist lock cord is a liabilty.
However the locking ring can be purchased separately and replaced.
I have replaced my ring. There is no need to replace the entire setup over the ring.
