(I was able to use 4ga since this is simply a "charging feed". If I wasn't running aux batteries, then I would've needed 2-runs/ea of 2/0 cable.....about 60ft of wire. Thus, in my mind, 2 aux batteries were actually cheaper than the large cable that I would've needed AND provides me w/ more power)
The 2 batteries in the engine compartment are tied together so if you went to either battery that would be sufficient; no need to run your inverter wires to both engine batteries.

Hope this helps.

best of luck.

That does help tremendously. So if Im just running aux batteries off the stock battery, I really dont need heavier wire? Im gonna do some research but thats good to know so I can save a few bucks!!
