That is true, but it was a good excuse to convince my wife we needed to spend the Big Bucks to buy the Smartplug! I bought it on Black Friday for a greatly reduced price, installed it a week later. I was (am) greatly impressed by it construction and it has such a positive connection between the RV and power cord. My TT is a 2017 that is going on 4 years old and when I took the factory installed socket out of the trailer I was amazed at how sloppy the connections were. Two of the four wires were barely tight, and if either one had come loose it would have caused a serious problem. After I found those loose connections I checked all the connections on my converter, finding one loose there as well. Loose connections result in excessive heat, excessive heat results in melted connections that can end up causing a fire.
