In the 'do I really need a surge protector for a basic trailer' thread, saw a lot about 'undervoltage'...many responses that 'undervoltage is more common that a surge, and causes as much or more damag...

Generally, the "accepted" or "acceptable" voltage range is 108V-130V for "120V" service. That is basically plus or minus 10% of the "average" of 118V.
At my home, I see typically 121V-127V, while camping typically the campgrounds I have been in are generally 115V-120V..
However, at one of my cousins that lives on the outskirts of a big city their electric voltages seem to run lower at 109V-119V on a regular basis..
For myself, campgrounds pose less of a threat than my Cousins place near a large city..
I am less concerned about over or under voltages than what happens when the power flickers on, off, on, off in rapid succession.. Lost a TV from one of those events and that was at my home, not while camping. General surge protectors do not protect from the rapid fire on/off thing.
A EMS might, but EMS might take the hit and burn up and is not cheap to replace either.
