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 in my 5th wheel. It was put there to run my cheap Hair 10 cubic foot fridge while on the road and overnight. I have a generator so it can be charged up at anytime. I want to buy just one good 12 volt battery to run that fridge if possible. Like I say being used just a few times a year. I also want to switch it back and forth to my TC. So what do you guys think would just one 12 volt do the trick. This battery is wired right next to the inverter with the proper gigantor gauge wire. As you can see I am not a electricity guro but I know at the time I set it up with the proper gauge wire, thanks to this forum.

thanks

    A 10+ hour stop over to sleep may put a bit of a strain on the battery and still for part time use it may work fine.
    You could test at home and get the second only if needed.

    the only reason I might hesitate to try the 31 would be if it is so large that you can't put a second battery in if needed?
