Anyone knows where the main hvac board control is located in a 2019 vegas 27.7?

What makes you think there is a discrete control board? Does it show one on you diagram from Thor?

The A/C has it's own control board.
The furnace has it's own control board.

These items are both controlled by the thermostat, if so equipped.
Or, as I suspect is your case, they are both controlled by the master "control everything in the MH", touchscreen control panel in whatever flavor you have.

'found it, behind the left wall in the driver side back cabinet - opposite to the wall where you would access the water pump

I too am a little puzzled about what is meant by an A/C "control board". On my newer 2021 Axis the A/C is controlled by the BMPro display and MasterNode. Those control almost everything on my Axis not just the A/C. Maybe that is what you are calling a "control board".

But again, maybe yours is different and has an A/C specific control board.
