Because almost all trailers don't have a total battery disconnect switch people leave them plugged in to keep the battery from running down. Because the LP gas detector is hooked straight to the battery it will drain the battery down to nothing if the trailer is left un-plugged. Unhooking the battery will solve this but that's a lot of hassle,. easier to leave it plugged in. It will also keep the battery totally charged.
Some people leave their trailer plugged in because they might be running something inside like a dehumidifier or heater in the winter.
