It seems we are actually talking about the same thing.
What I was saying is the truck doesn't need to detect that it has a trailer, though I am sure there are a number of ways to do that. Just when the accessory camera is on, it automatically replaces the backup camera in the rearview mirror...
If there is no DC 12V where I want it (or USB for that matter) I will put it there. I wasn't put off the Model S because it didn't have 12v in the trunk, I just tied into the 30A 12v line for the liftgate and put in my own 12V and USB charging plugs.

You will be able to get Wheel locking lug nuts for somewhere around $75
