is one 12 volt grp 31 battery enough for me
Well here is the deal. I at this time unfortunately only have the chance to go out a few times a year. Previously we were able to go on much longer more frequent trips. I have a 2000 watt inverter ...

Dave,
Your question, while interesting is patently unanswerable.
Things that will matter are:
The actual condition of the refrigerator.
The installation of the refrigerator.
The ambient temperature where the refrigerator is installed.
The amount of ventilation around the refrigerator.
The state of the battery when the power supply is disconnected.
And that is all I can think of right now.
I like and install Lifeline AGMs all the time. (Well not a lot since the start of the depression.) But, they are still lead/acid chemistry. That means that a discharge of more than half the rated capacity will probably cause a loss of capacity in the future.
If you want to go with lifeline, look up powerstridebattery. You may be better off with just something you can buy cheap unless you can install a pair of GC2s.
