We have a digital readout plug that we use at the campsite before plugging in. It shows voltage and whether the pedestal is wired correctly. My only complaint is when I plug the tester into my 30 amp converter plug it's always upside down. I'm getting too old for this 'bending over' stuff. :)

I have a Klein RT250 outlet tester that keeps the screen on for about 10 seconds after pulling it out of the outlet. Here’s a video I made about it last year: https://www.youtube.com/live/cy4e3hUnTz0?feature=share
