Hi,
Nothing that any RV'er can afford is going to protect their RV from a nearby lightning strike. It is the epitome of the Emperor's New Clothes.
I'm uncomfortable below 109 volts and turn off my air conditioner. The current crop of ems disconnect at 104 volts. That makes them useless to me.
50 amp RV's are at much greater risk of substandard wiring at campgrounds, so by all means use the top rated PI system. 30 amp units do not share these risks.
It is important to check both polarity and voltage before an RV is plugged in. The cost of the devices needed to do so is miniscule compared to the cost of an EMS, such as the top rated PI system.

Think about what would happen to the electronics in your rig if you are near a lightning strike or if there is some sort of power surge. Maybe the pedestal is not wired properly. An EMS will protect the electronics in your rig. It will not even let the power through if there is a problem at the pedestal. For us, it has protected us several times and we feel it is well worth the money. We have a hard wired Progressive 50 amp EMS.
