As long as you use a voltage protection system designed for this. A simple surge protector will not monitor and cutoff the power if it is outside of range.
A decent Power Monitor with Surge Protection will monitor for bad wiring, excessively low (below 104 volts typically), and excessively high (above 125 volts typically) and disconnect the power completely from your camper till that condition is fixed.
This is good and bad.
As discussed previously, your air conditioner powering up on an overloaded feed to your parking spot can cause the power to momentarily dip below the cutoff voltage and shut your camper down completely. It will then wait until the voltage stabilizes and (some) will reconnect you; others need to be manually reset.
This can be a real pain in the neck if you are at the end spot of a run and you are right at the limit for the service.
This is one reason I really like the Franks Autotransformer as it will hang onto that line and boost the voltage to get the AC going. Once started the amperage required will drop thereby increasing the incoming voltage where the boost may not be necessary.
