If you have a 4 pin trailer harness, it is not designed for battery charging, you'd need a 7 pin harness with a 10 gauge or larger wire from the vehicle's battery to charge the trailer battery.
In the case of an rv and some enclosed trailers , the position lights are not hooked up to the battery, only the interior lights.
