Dual battery install?

So the TT only has one battery installed. There is room next to the installed one to add a second battery. I would like to add one so when DS and I go dry camping. DW and DD will not go dry camping.

So any suggestions on the best method ?? Do you connect them together or do you switch the second one over when the first one drains down.

You probably have a Marine battery, which is a combination starting and running battery and not really good for either. For now I'd add another of the same, connected together.
When they need replacing I'd get two golf cart wet cell batteries, that will give you a longer life and more amps.

This is an easy upgrade--cheapest way is to get 2nd battery identical to 1st, but not the best idea to combine a new and old battery. Best way is 2 new batteries of the same mfg date. Car batteries not good for this, need deep-cycle type. Alternatively, for longest life, get 6-volt Trojan batteries and wire them in series for 12 volt. Otherwise, like sc3283 said, above--being sure to wire them in parallel like he says.
You might be able to also get 2 battery boxes on the same tray to keep them clean.
