DC-DC Charger Wiring Input Suggestions

I see pictures of carport, but no wire diagram?
Why are you using B2B charger? Do you have lithium battery?
On my Ford I was having idea of using on-board inverter to run 120V inside and use camper converter for faster charging where the small trailer wire was not adequate. But that was never important enough to me and sold the truck before doing it.

If you have the Power Pole connectors use them. Periodically clean grease the contacts.

Living in the NE with all the salt on the road, I did not use Anderson plugs when I wired my DC-DC charger as there was no way to adequately weather seal the connectors or cable penetrations when not connected. I installed two Pollak 2 pole recepticals, one on the camper and one in the bed of the truck. Each is weather sealed and I don't have any pigtail to worry about when the camper is off the truck which is most of the time in my case. I then made a connector cable with the female connectors on each end. Works great for me, but not the least expensive solution.

I also looked into trolling motor connectors but wanted something with a higher amp rating.

I ran my 4gauge/Anderson connection near the same place that the camper plug is at.
