2011 super duty towing problem

I have a 2011 F250 6.2 crew cab 6.5ft box 4X4. I got it out to tow my 30ft travel trailer Sunday back to the house to get it ready to go. The problem is that I noticed a humming noise coming from the truck when the engine is off and the trailer is plug in to the back for the brakes, lights,battery charge etc. It goes away when I unplug the cord from the truck it goes away. Has anyone else notice this on theirs. I can't tell if it does this when the engine is running because I can't hear over the engine noise. I had a 2003 F250 6.0 diesel and it never made that humming noise but then again it had 2 batteries under the hood. Just would like to know it I leave this sat. if it will be a problem.

I hear the same thing. But when I was hearing it was when I had the engine block heater plugged in then I unplugged it in the morning. I sometimes here it after I open the doors, but I never notice when and if it goes off. I have never had any battery issues so I figured it was just normal for these larger truck and all the electronics on them. I work with cable tv and you see some weird things with electronics and the way the work and keep working for no reason.

I haven't noticed anything like that with mine. It's a diesel but I wouldn't think it would make a difference with the trailer wiring.

I don't think it would matter what engine you have. You can only hear it with the engine off. It is a faint sound but doesn't seem to be a problem.

I have heard this humming too, but I did not have any external connections to the truck. I noticed it after cycling the key on and off without actually starting the truck. After starting the truck and shutting her down, no more humming.

I just heard it for the first time yesterday after hooking up to the trailer and shutting off the truck. It stopped after a bit.

Could it be the cycling of the electric fuel pump doing a return of the fuel back into the tank?

Or maybe it is the fuel pump priming itself with fuel. Thinking you open the door or plugged in the trailer, we are leaving lets get ready to start. Just thinking out loud.

I never had time to look at it when it happened. When we hook up to come home I will see if it does it again and will poke around and see if I can find the source.

There are always at least 2 ways to deal with the things you don't understand.
I am mechanically inclined, so I like to know what is at the bottom of that.
My wife on the other hand is not. When she had tire pressure alarm in her SUV, she just pulled the plug on the monitoring system.

Well mine never did it this time and I cannot get it to repeat the sound. I guess I will just have to wait until it happens and then look.

Just got back from one week towing trip and I think what the buzz is that the built in tow brake controller takes a few moments to connect. All these new electronic things take some getting use to.
