Long overdue update ........
Charger is wired. Ran a piece of flextite conduit between the tool box on the drivers side and the battery area. This is so I can run my incoming power cable from there. Also ran a pair of 8 gauge wires for the solar hook up. The solar controller will likely be mounted next to the batteries though. The other two glands re for my 2/0 DC power wires.
And in the box I have about 20' of 20 amp cord, and the two solar wires. Tools and fluids live there too.
And wires up to the inverter charger.
