One thing to remember is batteries loose capacity when they get cold. Only really matters if you plan on winter camping.
If going with AGMs, I would find room inside the camper for them so I didn't have to load them up each time or worry about them getting cold. If you don't have available cabinet space, you could easily conceal them in a step or under the cabinet overhang.
As said above, since AGM can be discharged deeper, there isn't much of an advantage with 6 volt batteries. Big advantage and reason I would go with 12V is if one of the batteries dies, all you need to do is disconnect from the circuit and the other battery will still be useable.
Bats would reside in the bed with a quick disconnect plug...you do have a point on warmth...the current bats are in an outside box so I have had no issues even in the cold. But something to think about...I bet there is a warm battery post someplace. THx for everyone's thoughts.
