What is recommended?

Thanks guys, one last question, does anybody know or have a rough idea of the best way to run the cables cleanly on a 2016 Silverado crew cab?

This many runs of power wire would destroy a steering shaft boot I assume.

I see 2 options:

drilling a couple holes in the firewall, but then this wire is thick enough to make it look like a snake lives under my carpet.

Or I run the wire under the body and drill through the floor pan in the rear.

The thing is my truck is brand new and I really don't wanna drill holes or cut in it

Any thing I am missing or is that pretty much the only options I got?

Right now I will be running either 2 runs of 1/0 or one run of 2/0 depending on what kind of distro blocks I find. And if I'm not happy with voltage response over ground I will double that for independent grounds back to the front battery.

I would run under the vehicle

I'll see if maybe I can get lucky and find a rubber plug I can pull down there.

There are plenty of options for rubber plugs out there. The important thing is the the hole(s) you cut are clean. If/when you sell the truck you can always use body plugs to seal off the extra openings.

bring them down the frame, and back up in the cab. Harbor freight has pretty decent unibits for like $6 a pair. Pick up some rubber/vinyl firewall grommets to bring them up, strap them with some air line straps, the ones with the rubber in them(could get them from a local heavy truck and trailer shop I bet).
