Adding a second battery
Hey folks, I am looking at adding a second battery to my travel trailer. My wife and I don't do any boon docking yet, but I want to be able to have additional power should we lose power ...

I would never pair an existing battery with a new battery. If you want two batteries (to double your AH rating) then buy an identical set at the same time, and always treat them as that pair.
Ideally yes, but in this case the OP already has one 12 volt battery of unknown age & condition - because he never detailed this information. :R However, if this existing 12 volt battery is relatively recent and has been properly maintained he could easily parallel it to a second new one without the world coming to an end and it's certainly FAR less costly than investing in a new pair of batteries. A friend of mine did exactly this, adding a second G24 to his existing year old G24, and both batteries are serving the purpose just fine. However, this point may be moot now that the OP has decided he's going to go ahead and buy a pair of GC-2s.
