I have been camping in RVs for 30 years and never have had any damage from the hundreds of parks we have stayed in. But I have only been doing so with a 50 amp rig about 6 years. Yes I have a Surge guard and use it. I have been checking electrical boxes and come across low voltage and you can find it often but not low enough to do damage. I may just be lucky but it is my opinion that campgrounds do a pretty good job for the most part on their electrical. Seems State parks 30 amp receptacles are the worst. Mostly all burnt up and loose.
Pogoil.
