I have installed solar that produces about the same on fair days. Even on a rainy day it's rare to get less than 1 kwh.

Operational needs are 100% met by the alternator (future state).

What's my motivation for high charging to house from the alternator? Pretty low, especially with 2 days reserve capacity.
On an 8 hour travel day, high amp charging is pretty unimportant unless you have high power draws while underway. But having the ability to charge faster is nice if you sometimes make a short hop to the next destination that's only an hour or 3 away. Of course, whether it's worth it depends on whether the faster charging is easy to implement or if it adds too much complexity.
