Fantastic, thanks. I'm going to read all that, one quick question....
If the 4awg is the largest you can get through one side but 0awg fits easily, did you consider/experiment with Positive running down driver side and Ground down the passenger side?
What I am going to do is remove 3rd row seats and build storage back there. I will have a secondary battery. So in order to get the most to the rear cargo area, do you think that would work? I see everyone running only down the Driver side and am wondering is there some issue with splitting the route and going with part of it in the Passenger side?
Basically my plan is the typical dual batteries up front, ARB Comp next to firewall. Fridge in rear but 3rd row seats removed so plenty of space to terminate large wires and build a rear distribution point. IOW, I won't need it in the jack compartment. In fact... if I could run 0awg easily, I might even consider the second battery in the 3rd row seat area behind the Fridge.
