Fan is not on and not using any lights. Plugged in to 15A 120v at home to keep batteries charged. If TV was on I probably couldn't hear it, but our 2007 3400RL never was this loud.

Do you have a transfer switch in your unit. I had one that had AC coils and had a hum that drove me nuts. Replaced it with one with dc coils. It is silent. My EMS internal was also noisy with a hum that I didn't like but my wife never noticed. I removed and bought a portable EMS and once again camper was silent.
I thought I would mention this as I thought my converter was humming until I followed the noise to both of the components I installed.
