Can I run my WFCO output to a REDARC BCDC?
My 2019 Brookstone 395RL currently has a: WFCO WF-9875 75 AMP POWER DECKMOUNT CONVERTER - 55-4708 I'm in the process of adding a REDARC BCDC1240D... and running #2 AWG from my 2019 F-350 DRW's batt...

5. So my next idea was... what if I take the output of the WFCO and feed it ONLY and DIRECTLY into the DC input on the BCDC?
This sounds reasonable to me !
I don't think you need #2 wire from the vehicle battery back to the BCDC. I would use a 50A MAXI fuse and holder, located close to the vehicle battery, which comes with a #6 pigtail. #6 should be adequate for the entire run.
If you dropped down to a REDARC BCDC1220 you could just use the existing wiring in vehicle. Yes, it will take longer to recharge your battery bank. How many hours do you typically drive in a day ?

- second question is, with live power coming from the WFCO and the TRUCK/SOLAR at the same time (wired together at the DC input of the BCDC), will everything play nice, or will something burn up or catch on fire?
You probably do NOT want all 3 power sources connected at the same time. I would use four relays to isolate things.
The first relay would sense 12V coming from the truck and disable the solar input (DC < 36V?) and a second 12V relay (rated for AC current) to disable shore power to the WFCO.
The third relay would be powered by AC (shore power) and disable power from the truck and the fourth relay would also be AC powered and disable input from the solar.
In theory, you could double pole relays, but having 12VDC on one pole and 120VAC on another makes me nervous !
