what gauge wire between two batteries?
I'm adding a second AGM battery to my truck camper. It's going to be under the bench seat in the back on the other side from the 1st battery. So their distance will be about at least 10-12 feet fro...

What sorts of loads do you have on the batteries? If there are no large loads (like a sizable inverter, for example), you'll definitely be fine with such wire, and could probably get away with somewhat smaller. Wire sizing is dependent on the current that will flow.
Do be careful to connect the batteries up in a balanced fashion and to do your best to ensure that the two interconnecting cables are the same length and gauge. Wiring them to be balanced means having the positive connection to the camper's systems at one battery and the ground connection at the opposite battery, so that current to or from either battery will travel through exactly one of the two interconnecting leads before getting to the rest of the world.
