    Should have listed front electric jack as a potential leakage location.

    Does the front jack have a small light you're not noticing during daylight hours? Trying to think what else is not connected to your fuse panel.

    12 volts is 40%. Way below what it should be after a full charge, then overnight.

    Disconnect the battery. Fully recharge. Disconnect charger. Check in 24 hours. If low, bad battery.

    8 volts? Check your emergency brake system. That is a lot of power to drain a battery overnight.

    Otherwise get out your clamp-on DC ammeter and find the leak. This is not a simple detector with 50 milliamps. Much bigger.

    Unless of course the battery is shot.

    Brakes, slide outs are not normally routed through disconnect. Check terminals at the battery for additional connections.

    If battery is indeed completely disconnected and fully charged, then it is spent. Know that some disconnect switches don’t shut down everything.
