I have been in a few places that I can say for certain I would not have wanted this type if device. Even though the trailer is scotched(by whatever means), I always want the electrical connection to be on the truck during hook up and unhooking for safety. When unhooking, I want to be able to control the trailer for those moments just after disconnect in case the trailer were to move. Kind of the same for when hooking, use it to make sure it doesn't move. But I know I worry about things like that way too much though, but I still do. For many though, it would save a step, although with that price tag??? Who knows....
