Does anyone monitor their AC voltage? Noticed that my AC voltage drops 5 to 7 volts continuously as measured from an outlet, when the Air Cond compressor is on. Do not know if this an issue with the shore power or maybe the wire on the 30 amp cable needs to be a higher gauge due to the length of the cable that came with the camper. Usually have at least 120 vac from shore power so this drop is not alarming. Although at some campgrounds when a lot of people are running their air conditioners have seen shore power in general drop to 108 to 110 volts. I do check polarity before plugging into shore power as everyone should to play it safe.
