There is more ;)
Running bigger than factory #10 wire to camper would make sense when you have 6-battery bank, but rule of thumb says you should not charge the batteries with current bigger than 10% of their capacity.
So 100 amp-hr battery should not be flooded with more than 10 amps.
Ford is the only brand that is having trailer 30 amp charging wire operated by ignition, so check if yours might already have it.
Bigger wire with bigger connectors might make sense when you use 12V for fridge, but sounds that you might already have all you need?
I definitely don't need tons of power for what I am trying to do, but Lance's wiring harness has the positive and negative wires as 8 gauge, and Lance specifically said don't use charge cables smaller than 8 gauge. More than likely, I will just match the Lance plug and run 8 gauge wires for charging.
My truck being a 92', I'm not sure what applies for stock wiring, but it looks like a lot is going on from the previous owner's 5th wheel setup. But definitely no big charge wires. Smaller than 8 guage for sure. I'd post photos but apparently I'm just not seeing how to do that with this format.
As for weather to run the charge wires through an isolator, or the constant duty solenoid AnEv recommended, I don't know. I'm still not super clear how they are different, but I can always keep reading.
