Battery down to 9.7v ??
We have one 12v battery in a travel trailer. After driving for 5-6 hours on Friday, we boondocked in Texas. 40s at night, 50s during the day. We only used 1 led light in the evening and the water pum...

its time for a new battery. anything under 12.8 is not good and its 5years old.
A fully charged flooded battery with no load on it should read in the 12.72 volt range, under load voltage will obviously drop, and the greater the load the greater the voltage drop. One can easily see voltage drop into the high 11s under heavy load but once that load is removed voltage will bounce back. Ideally you don't want to draw a flooded deep cycle battery down any more than ~ 50%, meaning it's unloaded voltage should drop no lower than ~ 12 to 12.1 volts. From the OP's description it would seem his battery is due for replacement.
