I guess I've been lucky. We stay at State CG's and a few private places and I have never seen low voltage. I have to admit though, we rarely get out of our home state and I imagine those traveling around the country and staying at the occasional CG that has older infrastructure could have peoblems.

There's nothing special about where you camp, look for low voltage and you will see it as "older infrastructure" isn't the only culprit. Here in S Ontario we have one of the most modern up to date power grid systems in the world and the Ontario provincial park system (2nd largest in N America only to the US national park system) is constantly improving and upgrading it's campground electrical service yet each summer I can absolutely be assured that low incoming source voltage to the trailer will be an issue, sooner or later. It's a matter of load on the system - take a park with 1000+ campsites, 30% to 40% which are 30 amp electrical, pack the park completely full during the busy summer months, and once all those with A/C start drawing from the system voltage does drop, alarmingly. I wouldn't ever plug in these days without the protection of an EMS.
