I believe in most of our coaches, the Aladdin gets the individual leg-voltages from a wire plugged into the transfer switch. A pair of toroids report the leg voltages to the Aladdin.
Anyways, where I was going with my post was the RV parks power system is probably underpowered for a full park with all the RVs running their ACs. This would pull the pedestal voltages to a point low enough to make many electrical devices in the RVs act weird. If you have a surge guard, either hard-wired or portable, I am guessing it would have kicked your RV offline from the pedestal.
