We have a 2018 3560RL Montana and we can hear a low hum when we stand by the stairs. That is right next to the breaker box and switches in the cabinet above.
We can power down the frig and turn off the battery disconnect and still hear it.
I thought it might be an inverter because we don't always hear the sound.
where would the inverter be installed and could the sound be from something else?
Anyone experience this.
