Connecting 2 batteries together
I have space for 2 batteries where I currently have one. The one I will be adding is identical, except it is about a year older. Am I right, I need to daisy chain them?

There are a lot of myths about paralleling batteries.
For the most part the only thing you need to concern
The Connecting cables need to be large enough (Same as the cable that runs off to who knows where)
And the polarity.
Most everythign else the batteries will work out by themselves
In some very high current installs there is more (Load Balance) But you are into the hundreds of amp loads before that's a concern.
With GC-2's there are additional concerns but since you are not going that route. That is all folks.
^^^ This
If you were talking about a 1500amp-hr @12v bank feeding a 3000w inverter that will be used to run the air/con or some other heavy duty system, mucking about with load balancing becomes important.
For a couple of basic 12v batteries tied together to feed minor house loads, it's largely irrelevant. Even running something like the main tongue jack might be unbalanced but as soon as the load stops, the batteries will balance themselves.
