We don't havw what ifs with our's. On Fords. The 7 pin is dead as long as the TV switch is off. In other words. It is already disconnected.
Another "Better Idea" from Ford.
I also understand the Dodges do it as well.

Thanks for all the answers.
Our TV is a Silverado Allison Duramax so I do not know if the 7 pin is cold when the ignition is off so I think I will un plug for the overniters in transit.
Thanks again

More than likely you are hot all the time if you are stock. Easy to check with a voltmeter and good info to know. I would check it right when you turn the ignition off and then again about an hour later (dont unlock or touch the doors). Sometimes there is a timer on the accessories and it will shut off things after a period of time.

On my Dodge, I know that the Charge Line is cold, but the Brake Controller is hot, which would provide a small power drain. Not sure about the back feed from the Converter or House Batteries to the Truck though. Might have to play and see what happens.

Many GM's are HOT all the time. My 2003 K2500 Suburban was for sure. I could run the power jack off the truck when the battery was out of the camper.
My Ford now has a relay in it. It's off with the ignition.
Hope this helps

The battery terminal in the trailer cable was turned off when the engine was off. But, it's live on our Chevy 2500HD. I installed a constant duty solenoid in our DP to control that circuit so the toad was charging when the DP was running, but disconnected other times.
Since we've had an electrical protection system in every RV we've owned, the TV is protected by it as much as the RV is.
My larger concern with disconnecting the trailer cable without unhitching was that we'd forget to reconnect it and drive off without trailer lights or brakes. Since we've had 2 Hensley hitches and Hensley's don't play nice when the TV brakes without the TT braking also (and quickly, too) driving off with the trailer cable disconnected can easily lead to a serious mess.

I always unplug the trailer from the truck when parked overnight. I have experienced enough electronic component failures to not take the risk of a failure that is not necessary. Take the 30 seconds to unplug and plug back in.

What kind of controler do you have? My Prodigy is hot, even with out the TT, but it goes to sleep 15 min after the truck is shut down.
