Loud buzzing when applying brake
I have a 2007 Fleetwood 325rkts. I have never had previous issues. Now I have purchased a 2020 GMC 2500. After connecting the camper to check lights I have a loud buzzing coming from under the cabinet...

I'd check the voltage for lights, turn signals and brakes. I'm wondering about compatability between 13 yr old brakes and new truck brake controller. Or maybe a truck issue? Any chance you could try it on a different trailer?
