One thing to look out for is the type of controller your trailer has. If it's a relatively new trailer, it is likely equipped with a four stage controller. If it is five or so years old, it may only be equipped with a 3 stage controller.
A four stage controller is designed for long term battery storage with little or no load. It will ensure you do not boil your batteries by reducing the voltage when the battery is fully charged.
A three stage controller does not have this feature.
So in other words, know which system you have before you plug it in with no load for a long period of time.
