I installed a smart plug on my boat after finding the 30a twist lock partly melted, but discovered that I never unplug it, so it could have been hard wired instead. My van is hardwired, the cord is stored behind a small plastic door, so there is no danger of an inlet plug melting. I simply open the door and pull out the cord as needed. If you have a similar set up, hardwiring makes sense, but if you need to be able to remove the cord after each use, the Smartplug is a great improvement.
