Actually, as it turned out, I awoke about five days later to hearing the motorhome generator running. The PI EMS said it was an overvoltage trip and the voltmeter was reading 133 and 134 VAC when the real input voltage was 122 VAC.
I shot note to PI and they shipped me a new logic board which I'll get installed soon. A friend who bought the same unit in 2019 as I did told me he had the same problem, the voltmeter readings drifting a lot over several days, and he also got a new logic board under their lifetime warranty.
