If I understand you are having issues with the fridge while towing? I don't know what your tow vehicle is but make sure the relay is installed for the charging circuit to the RV. I know on my F150 the relay was in a bag in the glove box.
You can check at your 7 way plug for 12v on the connector labeled for auxiliary power on the diagram refenced below . Look at this diagram and the 7 way RV style car side to see if you have 12 volts when TV is on.
There have been some posts where others were having problems with the battery keeping up. I have the single 17 cu ft fridge and have run for over 12 hours on battery with a couple with a couple of hours of that time my TV was off and parked.
I always check the inverter whenever I stop, usually every 3 hours to ensure it is still running. The inverter does have a low voltage readout I think.
