The price difference isn't huge. We're talking $10 vs $16. I don't think routing should be a problem either way.

Second life would be to move these wires to a new vehicle. So, maybe I want to have a little extra length, which may push me up in size.

Good points.

Thanks guys.

I think I'm going to go with 10 ga or maybe even 8 ga. This allows me to upsize the setup later as I would like to find a dc-dc converter that can handle more than 20A. 6ft of 10 ga should be good for just under 40 amps. 6ft of 8ga would be good for 60A.
