My New Solar System Overview.
My New Solar System Overview Yes, it cost a pretty penny and took about 3 days to plan, remove the old system, and install the new system. 675 watts solar, 400 AH Lithium batteries with heat and col...

Yes your correct the truck/camper circuit is isolated from the rest of the electrical wiring/connections in the camper. They are only energized by plugging into the 7-pin plug.
Like you my solar panels do most of the heavy lifting as far as replenishing the battery's and the dc-dc was just to have a more favorable charging profile for the lithium battery's as well as a way to keep them isolated so no discharging could occur.
It also limits how much charge your truck alternator will supply (18a for me ) as supposedly the lithium batterys will sometimes want to take a larger amperage draw if they are depleted and in need of a large ah charge. Possible more than the wire size feeding back from the vehicle to the camper.
