I have a 2020 Sierra 5th Wheel with 2 AC units. The bedroom AC unit compressor would cycle on/off then mostly be off.... much like you're describing I think. It turned out to be a bad thermostat that my local FR Warranty Service Center replaced. AC has worked great in bedroom ever since.... over a year ago now.
One final comment.... About a decade ago my workbuddy nicknamed me TwoDogs. I called him Mighty Cheeks.
More stories than room for here but makes me smile.
