Is there anything to be done? I have turned the batteries off and used a batt charger off an extension cord in the past, no problem. (The problem is when I plug the 50 amp coach cord to an adapter to the 125 receptical.
If the GFCI doesn't trip right when you plug in, what is cycling on/off at a later time?
These trip when an imbalance of current between the Neutral and Line exists, in the USA they trip with 5 milliamps of current... and because everything is connected to one circuit for storage power... appliances, devices, and cords with 1 or 2 mA of current leakage, will not individually trip the GFCI, but together, they can.
Also remember that electricity travels in a circuit and will attempt to return to origin using the path of least resistance. When that path is interrupted or fails, current will still seek a return path.
Mike Sokol draws pictures of current flow to help him find the places bad things could be happening. It's a good thing to emulate.
