Time for an update:
Installed a tool box. Got the bed Rhino Lined by Rhino Liner of Orange County. They did good work and were super helpful.
Inside the toolbox lives my 100 Amp-Hour battery which drives my radios. The battery is isolated from the rest of the truck using a West Mountain Radio PwrGate PG40s. This is a pretty neat device which only connects the battery to it's charging source (which in my setup is the trucks main battery) when the incoming voltage is high enough, which it only is when the alternator is running. The PG40S also limits the amount of charge current provided to the battery, in my setup I have set it for 10 amps. This limits the current draw on the trucks electrical system (good thing) and it prevents overcharging the battery (also a good thing)
The connection between main and aux batteries is 2 gauge cable to prevent voltage drop and is protected using 60 amp maxi fuses, located right by the power source (main bat)
The battery is held down to the hardwood base plate using a ratchet strap. The base plate is in turn bolted to the tool box floor.
Here's how the truck sits as of today:
Next up on the list:
ARB air compressor to air tires up.
Rocker panel protection
Install HF HAM radio (just need to figure out where to put it......)
