Our 2022 3791RD has the TPMS booster and the propane/CO detector powered on all the time based on the way those devices are connected at the "giggy box" from the factory. I can tell you that my leveling system is off completely once I turn off the power at the "giggy box". You can check yours by trying to power it on with the giggy box switch set to the off position.
Since I have the 400i solar system, the overnight drain gets recharged daily as long as there is some sun. Your 2023 should have at least 200 watts of solar, so if you are parked outside, turn off the "giggy box" and inverter, but leave the solar turned on. Then check your system after a few days to see if the solar is recharging enough to compensate for the overnight drain. If not, you will need to disconnect the batteries completely.
I've pulled the cover on the "giggy box" and may at some point move those two devices so they are controlled by the switch.
Good luck!!
