A note - leaving the 7-pin adapter connected to the car while the car is parked/off and the trailer has no shore power will result in a significant drop in range. How significant? On the order of 30-40 miles overnight!
I thought I noticed this on my first boondocking trip with the camper, but then second guessed my memory. However, on this recent trip I have confirmed it. I suggest anyone with a trailer disconnect the 7-pin while camped overnight. It's far too lossy to be worthwhile.
Hmmm...wonder if there is something to what you noted after all. May have to check with my trailer.
