Assistance wiring (2) Orion XS 12/12-50 DC to DC Chargers in Parallel in a GMC 2500 Duramax

Hello,

I am looking for some assistance with how to wire two Orion XS 12/12-50 DC to DC chargers in parallel in my 2025 GMC 2500 Duramax (with dual alts). This will be a part of a full new system I am installing in my Cougar Travel Trailer–which is where the Orions will actually live. I am just looking for feedback/schematic on how to wire the truck side of things at this point as I want to get the wiring installed from under the hood back to the hitch receiver. Any feedback is appreciated.

Thank You,

Tim
