keep away if in Penn Dutch country

Keep away from Pennsylvania Dutch campground in Bernville, Pa. They expanded their sites without expanding their capacity so we keep getting voltage readings below 104 volts on both lines of 50 amp service. Had to run the generator to use ac or anything else. Worse part is when we talk to the office they claimed they had no issues and we were free to change sites. We did and didn't matter after we found two other rigs had done the same. One tried 3 different sites with the same result. Just keep away.
