Unhooking electric from tow vehicle
Question for when pulling in a site for the night and not unhooking from your tow vehicle: when plugging into 30 amp service at the campground, should you unhook the electrical from your truck?

The technician in my walk through for the previous 5th wheel advised unplugging the umbilical from the truck before hooking up to shore power. I occasionally forgot it and it seemed to coincide with blowing the fuse on the 12V trailer circuit in the truck, but not every time. I received no such advice on my latest 5th wheel, often leave both plugged in when reaching a site until disconnecting the truck from the hitch and have not detected any problems. If you overlap the connections, many of the clocks, etc. that run off the 12V trailer system do not have to be reprogrammed.
