Connect + to + and - to -. Connect the negative from the trailer to the negative on one battery and the positive from the trailer to the positive on the other battery to get even distribution of voltage.
Correct...and good advice.
Also probably best to start with 2 new fresh batteries. The system will only be as good as the weakest (old battery). The old batt. may draw down the new one that you add.
