Battery Fuse for Solar/Charger System
From the new solar/charger system was planning to run 6ga + and - wires right to the battery terminals, not tied in anywhere to the existing trailer wiring. Was thinking about using a Blue Sea 519...

Yes, load cable is separate, and there is a voltage sense wire in Rogue, but you connect the loads wire in parallel to the controller wire. Usually - on the bus near controller. When controller is raising the voltage to compensate for drop, the load wire and all the appliances are getting this raised voltage - not the "correct" voltage that is on the battery terminals.
The only way to avoid mistreating your appliances while dealing with too high voltage drop is to connect the loads cable directly to the battery.
Edit:
My bad. Voltage drop calculators are to be used with "one-way" distance. Yes, <2% drop with AWG 6.
Now, with converter pumping 60A through the same cable - this is how I see it. Converter has no voltage sense, so there will be uncompensated drop and lower voltages on terminals. Your 12V devices are safe then, but charging will be under-volted. Though with converter it is always undervolted, with those long #8 wires from converter to battery. I wouldn't trust my WFCO with anything but floating charge.
