Helpful Expert Reply:

Leaving anything hooked up for power will cause a drain on your towing vehicle battery. The 12V accessory line on your trailer connector is designed to maintain a battery on your trailer.

You may want to consider installing a battery on your trailer and use a battery charger like part # CTEK56353 to charge the battery when land power is available. This would make sure your towing vehicle battery stays charged when you need it.
