I just bought a 2021 Cougar 29 MBS. I will be tackling this same job next summer. I live near Rockford and it looks like your in Danville.
I will be following what your doing.
It looks like your using Victron Energy products. They have an app that may help with your calculations.

Also, I like the Circuit Wizard from Blue Sea. You can find it in your app store.
I also follow a guy that is do this in vans and his info is a lot of help. Explorist.life. He is a trainer for Victron Energy. There is a lot of good info there.
I am currently rehabbing a 1990 Toyota Sunrader and will be adding solar to that. The sites above have given me lots of good information.
If I can help let me know.
