Nope......I never unplug trailer umbilical cord from truck unless I am unhitching trailer. If trailer is hitched up...umbilical cord is plugged in.
If I overnight I leave it plugged in even when hooked up to shore power as it will have no affect on truck electrical system.
Never driven away with any utilities still connected...GF double checks that we are disconnected.
BUT I have left a couple water pressure regulators, a water filter, a sewer fitting and a couple of pliers behind. That's when she started checking me :S
