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 ...

The two story Lifeline Group 31 is the Lifeline GPL-30HT rated at 150 Amp hours.
When looking at its specs, one might infer the plates are even thicker than the gpl-31XT, and not just taller.
Much more weight for only 25Ah more capacity, and not much more cca either.
I briefly had a GPL-31XT (125AH)in my possession when it was new.
its fully charged resting voltage was 13.16v or higher.
it had absolutely no issues sucking up 100+ amps from a fast spinning capable alternator when depleted to 50%.
Impressive battery.
Not sure if it can handle a residential fridge for long enough for the OP, but if the height is there to fit this tall boy GPL-30HT, then Me thinks it would a very good option, as long as one can be bothered to high amp recharge it at no less than 20% rate, and can regularly achieve a true 100% State of charge
