Cable routing from driver side rear to bed

I'm installing an auxiliary switch that will run from my house battery in my bed to a dc/dc charger that is installed behind my rear seats. I need to run two 1/0 cables out of the cab one that I will run into the bed and one I will run under the chassis through the engine bay and to the battery. Anybody have any ideas for this? So far I'm thinking about drilling a couple holes and throwing in cable glands.

 

This is what I used

$19 Blue Sea Systems 2204 TERM FEED THROUGH STUD 3/8" RED

I’ll add on to your post a little bit for the other people here-

Blue Sea is a high quality brand, so don’t be scared that it’s for sale on scamazon…unless of course it happens to be a knockoff Blue Sea product.

 

Very nice what part of your bed is this on?

 

Driver’s front corner just behind and below the cargo tie down points.

 

What did you use for those floors man they look amazing! If you have more pics of your interior would love to see. Also how did you connect the floor to the bed did you use rivuts?

 

1/2” birch ply and a layer of EVA foam boat decking

 

Did you just lay it in or did you fasten it to the bed?
Did you use FRP board for the cabinets?

 

1/2” birch is bolted to nutserts in the steel subframe.

Cabinets are 10 series extrusion for the framing and 1/4” ECM for the paneling

installed threaded inserts into the subfloor so I can easily unbolt the cabinets if needed

 

Sounds like our thinking was pretty much syncing. Thanks to Ton for your help. I'll drop a link to my build when I get it going. Installing some of the electrics today.

 

Oops, I thought I posted more pictures of the floor system. I welded up a steel subframe that raises the birch subfloor up 1/2” making room for 1/2 foam insulation under the wood. The frame is mounted to the bed using the existing bed bolts. I added two extra nutserts for good measure.

 

This looks great man I'm going to see what I can do. My thoughts were to try and keep it as light as possible using 8th-in Birch. I was going to fill the slats with quarter inch Marine decking strips and put the Birch on top of it with more marine deck on top. How much weight do you think the substructure added?
