On my KR if I disconnect with the truck shut off, when I restart the truck still thinks the trailer is attached and I have to deselect the trailer.
If I disconnect with the truck running it "knows" the trailer was unplugged.

I do the same and it will let you know when you have a light problem. Also keep track of each trailers mileage for your maintenance

That's interesting. I almost exclusively disconnect the trailers with the truck off and it always deselects the trailer on it's own.

i towed my travel trailer for the first time last weekend. Today I checked to see if I needed to deselect the trailer or not after seeing this thread. The first screen on the tow menu clearly stated “no trailer selected” HOWEVER when I scrolled down and selected my travel trailer it was still racking up miles! I was pulling out of the driveway and saw it adding 10ths of miles as I drove. I had to select the trailer and deselect it so it would stop adding miles. There was a pop up that said no active trailer. Poor programming IMO. I would think If the computer knows nothing is connected it should stop putting on miles. Maybe it does it like that for trailers that it doesn’t automatically recognize?

If I disconnect with the truck running I get a message that the trailer was disconnected. But unless the trailer is deselected the mileage keeps racking up.
Looked in the owner's manual and saw this on page 116:
Note:Once you select a trailer, it remains active until you set it as no longer active. An active trailer still accumulates miles even after you physically disconnect it from your vehicle.
