I think that I know what happened. I failed to mention that I was in the high Sierra mountains at about 6000-7200 feet when this occurred.

I have a 15k btu in the front and either a 13.5k or 11k in the rear. The manual states that the 5500watt gennie loses 3.5% power for every 1000 feet gain in elevation. Thus, I was losing about 23% of the gennie power. It couldn’t keep up with the ACs. This has been a good lesson.
