How was that night out in the TT?
To make things a little easier, you should pick up a plug-in volt meter (plugs into your TT's 12VDC outlet) for your TT (there are all kinds on Amazon). This will show you the voltage of your battery(s). The battery rule of thumb is you never let the battery voltage drop below 12.0Volts (50% rule). This will allow your battery to live a long life. When you are not using your TT and you can not plug it in to shore power, you need to remove the main TT fuse that is usually located by the battery. This will stop your battery from discharging. When you discharge a battery to where it is below the 12Volt point, it life is shortened. A lot of members install a battery disconnect switch between the battery and the TT, which makes disconnecting the battery much easier.
Also the heating system fan will run down the battery in one night if it is cold and you are not hooked up to shore power.
