I recommend 4/0 AWG cable per each battery terminal in addition to the disconnect. The position on the trailer can complicate matters depending where you install it. But generally pretty straightforward install with the manufacturer's instructions.
What disconnect did you buy? This matters because it could be a simple on/off switch or a more complicated dual 12-volt switch that allows battery 1, battery 2, both or off.
