An important question- how are you determining the batteries are back to "full?" Are you using the sensor that also has the tank levels? With the solar panel attached I would think it would show as "full" around 10:00- as that would be around the time there is enough amperage coming off the panels to start charging the battery.
The best way to test the battery is with a multi-meter; and at least 30 minutes since the last time you either put power in or drew a significant amount of power out. The easy way for you to see that for yourself is to pull up to your campsite and unhook. Then check the battery level (should be full.) Run the water for about 30 seconds. As soon as you shut off the tap check the level again. If it isn't showing 1/3 it will definitely be showing 2/3. Then wait 15 minutes and check the level again; it will be higher.
The problem is those level gauges show voltage coming from the battery; not amps remaining. While amps remaining does affect voltage, the voltage is also affected by recent draw and charges.
As for your fridge; with it having a digital readout it might use a little more. I would guess not by much as I'm sure the electronics in mine are also measuring temperature to a certain extent.
