2017+ Dual Battery
I am not understanding the DUAL BATTERY setup in the current Super Duties...are they isolated? if so, and the 'primary' battery dies, other than physically (with cables) jump-starting it would the seconday battery be of any use? Is the dash-mounted 400w INVERTER AC receptacle 'wired' to one battery or the other? Same for the UPFITTER SWITCHES, are they wired to one battery or the other ? Does anybody have a simple explanation of how these two batteries are addressed in the electrical system? Thank you.

Thank you to both of you who responded, I guess I was overthinking what they may have done...I did see the cable setup but thought there was more than met the eye...I like the answer of the two batteries just being installed in parallel.
