I'm with most of the crowd here- You need to measure the

The only thing I can imagine making it act like this is low voltage when on
My money is on a corroded terminal at the current limiter near the umbilical service box. A poor connection here will result in reduced voltage to the camper when operating on battery (even when the batteries check good at the battery.
A bad or corroded ground connection at the frame. Follow the black/white wire from the battery to the frame.
