My Thor requires engine running other wise its locked on main power panel. Awning and bunk bed are also locked. I can only get unlock with engine running. The main battery switch is on, and use button on. If not nothing will happen. I was trying to find out what to do if I can't get engine started after camping and need a tow. But a lot more things are not going to happen as I will have no air to raise home back up or retract levelers. Hope it never happens. Just seeing what others have done to keep power up. Right now it's a hit or wait for power to get above 13 volts.
