Rear Air Conditioner shudders

[Bob and Jeannette]

My rear AC unit shudders the entire trailer. It’s more of a low frequency vibration, it’s not terrible but we can feel it front to back. Is this normal? Front ac does not do this.

You might check the screws that hold the A/C down. If they are loose, that might be allowing the unit to shake.

I’ll look, it’s more of a low frequency vibration around 1khz that we hear and feel most in the bedroom. Almost feels like air pressure.
