Noise from inverter

[airgrunt82]

'21 3500 with the 400 watt factory invertor to the bed. When I turn it on, sounds like a busted cv axle trying to turn. Can here it at idle and driving. Open the window or door and the noise is gone. It's for sure the inverter as it also goes away when turned back off. It's absolutely mind blowing. I'm using it to power some Christmas lights that are wrapped around my ladder rack (I install Christmas lights from mid October to December. Anyone one else have this is and/or a solution (besides just turning off), I'm really want to know why it does this.
