Surge Protection-EMS
I have read most forums regarding protection by Surge guards or EMS systems. It seems that as the RV parks/Campgrounds age, the electrical systems start to get weak. We have stayed at Jackson Rancheri...

I'm currently plugged into a good 15 amp shore power. However the cord to reach it is 100 feet of #12 wire.
No load voltage is 115.
Load with air conditioner dips to 94 then rises to 102. The air conditioner does have a Microair easy start kit.
So, if I had only an EMS that disconnected on low voltage, I'd not be able to use the air conditioner.
Another issue is the low voltage disconnect value. I'm NOT a happy camper below 107 volts, but the EMS units disconnect at 103.5. Yes, I know there is a 10% tolerance. But as the air conditioner runs the voltage drop may become greater.
But with an autoformer the voltage to the air conditioner rises to 118.
I also have the load support feature of the Magnum inverter charger enabled.
The Autoformer allows me full use of the RV and is cheaper than the EMS.
