Rethinking a few things

I have been struggling with the placement of batteries and items under the hood. I am now considering keeping all the batteries together in the truck bed enclosed in a box. The reasons are keeping the batteries together will be easier to insulate and keep warm and I originally had too many batteries too far behind the rear axle.

It has gotten cold in the garage and the heater isn't cutting it, so work has slowed. Also other things have been taking priority.
I have taken the instrument cluster out of the dash and disassembled it to fit some digital meters into it. I have also figured out where the link 10 watthour monitor will be mounted.
