12v vs 6v battery question
I've got to replace my 2 batteries on my TT. We typically camp with power so we don't boondock. We do have a residential fridge, with an inverter, and the batteries to get a little charge from the ...

Doesn't matter either way 6v or 12v.
If one 12v fails the other one will not function properly after it has been discharged by the faulty one. :W

Only possible if those two 12 volts are run simultaneously in parallel ... run them sequentially and one has nothing to do with the other. With 6 volts one has no choice but to run both together at the same time. Touche. :W

But you gotta tie them together for your inverter use: Touche X2
No I don't, nor does anyone else. I only use a single G27 and load support with my truck when under heavy load from my 1000 watt PSW inverter. When the inverter is under relatively light load I still use it but don't even bother with load support - works like a charm. :B With dual 12 volts, run one as a primary, the other as secondary, wired through a Blue Sea m-Series 6007 Dual Battery Switch.
FWIW, I also run my propane tanks sequentially - don't care whether anyone else approves or not. Touche 3. :W
To the OP - I personally would prefer dual 12 volt G31s if for no other reason I can always run on one 12 volt but never one 6 volt, but that said if dual 6 volt GC-2s fit better where I wanted to put them then I'd go with them instead. Don't let forum pundits with their so-called "expertise" sway you one way or the other with their armchair biases - either will work just fine for your application, albeit with some differences that are worth understanding but not worth losing sleep over. ;)
