We have been to two places that had voltage below 100 volts. One was in a cool climate. Everyone was running space heaters. The voltage dipped below 95 at breakfast time when they also turned on their toasters.
Another place dipped below 95 over July 4th weekend. Everyone was trying to run their air conditioners.
We hook a Hughes Autoformer voltage booster up when the voltage drops below 110. Unfortunately, the device will only function down to 95 volts. At that point it gives up, but does not shut down, and continues to feed the super low voltage untouched.
This is why I always use an EMS with the voltage booster.
We did have a microwave die before we understood the flakiness of rv park power.
Many years ago we were camping in a pop-up equipped with an air conditioner. It was really hot and humid. I was awakened by a loud humming noise from the AC. the compressor would not start with the available voltage and would kick off after trying to start. I turned the thermostat up so the compressor would not try to start. After a while I turned the thermostat way down and it started. With the temperature set as low as it would go the compressor ran continuously with no issue. It became pretty cool in there but the AC worked very well from then on. Thanks for your efforts to inform our community. Hoping to see you somewhere this summer. - Jim
Low voltage, 106 - 110 fairly common. Worst ever was campground in upstate New York, finger lakes region. Voltage about 104, campground owner said they were out at the end of the line and it was an electric coop and they couldn't/wouldn't do anything about it. Campground was not 1/4 full, but it was a hot day. Wound up using generator for anything beyond battery charging.
My microwave seems to cook more slowly on lower voltage, e.g. 108 vs 123.
I've used a Progressive Industries PT30C since 2014. It has shut off the juice due to low voltage several times over the years. No damage in the camper. Not sure why, but last summer my unit finally went crazy, reporting high voltage (170 to 180 as I recall) and shutting off the power. I used a separate VOM and found the pedestal power was in the normal range. When I got home I duplicated the issue with my household power. Then I contacted Progressive Industries.
I expected to buy a new unit, but Progressive asked for pictures of the original receipt, the plug, and the receptacle. I sent those and they replaced my dead unit with their latest equivalent model, PT30X at no cost to me.
I think they are a great company because of the way they back up their product!
We were in Memphis last week. My Progressive box tripped out on low voltage several times. I read 108 on the display when it was still passing current. This was on a 30 amp site and it was 95 degrees and the park was nearly full.
My Surgeguard cut us off from low voltage twice, once at 103 volts and once at 102 it also saved us from high voltage twice, around 145 volts to neutral from one leg only. The high voltage happened around 7PM while outside of Montreal Canada that effected most of the campground, luckily the 30 amp plug was powered off the good leg. The next night at about the same time it kicked us off again. After those 2 nights everything was hunky-dory for the remaking stay. I worked in the power production and also distribution business for 40 years I chalked it up to switching on the lines to a transformer that had a mispositioned tap. Our neighbor was not using any type of electrical protection and was lucky not to have damage, he did put his dog bone in and lived off the 30 amp
I have not had any problems in ten years.
BTW
Thank you Mike for sharing all your experiences and knowledge. I have learned a great deal and you have saved me a lot of $ and kept my family safe.
My progressive ems-pt50x has saved the day from low voltage damage several times. I won't plug in without it!

Don't know how low it went, we were away when my Progressive shut my power off for low voltage set for 105. No damage, it save me more than once.
No low voltage problems.
105V was the lowest encountered prior to installation of my Progressive EMS.
I have not had any appliances fail in 14 years. 🤞
We had 106 volts and our air conditioner kept shutting off. I turned the unit off so it didn't keep trying to run.

My Sureguard protected my RV electrical system by cutting off the power every
times we had low voltage
It might have gone lower but this is where my EMS cuts me off.

No problems yet
My PI EMS-HW30C cut off several times in an overloaded campground. Moved to an less crowded part of the campground; all ok in the new location.
