I just read the whole post and have a couple of comments:
1. I was thinking from the beginning you need to boondock to prove to yourself what most of us know about the WFCO. It is not up to the task for boondocking. I've had prior experience with them as OEM chargers and always ended up replacing them.
2. On the bench is one thing but when camping and charging, if "ANY" load is put on the system (switch on some lights) it will immediately revert to 13.6 mode and stay there. This was confirmed to me by my own test and by WFCO tech support. It is like the WFCO senses a change in load and says "ok, user is using so I need to go into converter mode".
3. If you are as OCD as you say you are, I see a Trimetric in your future
4. My current 2015 camper came with a 80 deck mounted WFCO converter. I could never get to go into boost even if I pushed the boost button. I replaced it with a 70 amp PD with charge wizard. I can make it go to 14.4 volts (wish I could get 14.6-8) for 4 hours at any time by pushing the button. My solar does 14.7 when I have sun.
5. My 80 WFCO is now a shop charger as I connected some #4 cable to it with battery clamps.
