I'll say it again they do hum. Now don't keep chasing you tail find a few other units while camping which have a transfer switch ask them if you can have a listen ,I bet you most or all will say please do.I had mine for 15 years and sold it that way. My new A class has a manual plug in and out no noise with that.
