Battery cable size
I want to replace my single battery with 2 Grp 31 AGM deep cycle batteries. What size cable should I use to hook the batteries together? Thanks

If you are going to run a decent sized inverter, you should go with the same gauge that your inverter requires. As stated, make the jumpers the same length and connect trailer load to one battery and ground to the other. I have a 2000 watt inverter and built my own 4/0 cables using welding cable purchased from Amazon. The welding cable bends very well.
