You made a good decision with the PI unit. We had one installed six years ago when the coach was new. Over the years it saved us twice at CGs. But there is another great reason for PI. Twice I've had problems with the unit, neither time a PI issue. Once the inside display went blank but we still had power, and another time after parking in storage, no power to the unit. We store indoors with 15A service to keep batteries and frig going. Both times were on a Saturday morning. I e-mailed PI and received a reply from the president of PI within the hour, on a Saturday. Display problem was the connector for the display had come loose and in storage, at his suggestion, I changed the 30 to 15 adapter, problem solved. Great customer service.
