Maybe I'm gambling, but I don't use a surge protector. I do measure the campground voltage several time throughout our stay though.

You are, just as is everyone who doesn't use an EMS to protect their trailer's electrical system. Are these devices "perfect"? ... no, of course not, rarely in life is anything "perfect" but using one is a darned sight better than ignoring the many campground power anomalies that can and DO occur. Typically my own Progressive EMS will disconnect from campground power 3 - 4 times each season, even has disconnected here at the house where I park our rig during the camping season. These used to be novel items a few years ago, now an EMS is mandatory IMO. Your money, your call, but don't whine later if you choose not to but at some time in the future lose your converter, or microwave oven, or A/C, or whatever. :R

Either I live in an imaginary world of "alternative facts" or these errors really did occur. :W
