Wiring - Charging

[IamJEEP]

I agree with that 100%. My first thought was a plug to charge the battery, seperate from the tow wiring harness.
I would think I would need heavier wiring than a trailer plug which is about 14 -16 guage. The wire from your alternator
to the battery is about 6g.

Yes but that's a short run from the alt to the bat. You would need to up-size the gauge to make up for the length if you want the same amount of amps to get back there. I'm thinking at least 4 gauge from the front to the back.
