I’m not sure if the configuration of the 2/00 would allow it, but I’d recommend protecting the battery leads with split loom. The ambulance upfitter did that on my rig and it seems to be a good way to avoid unwanted battery explosions.Running wiring for the back up cam. And here is the busbar capable of handling the 220 amp alternator output minus losses, to the battery tray where this will reside. Connects to a new 2/00 wire that will charge the house batteries Ill be placing inside. Small gains!
