And an update to that:
We now have 200 amp-hours of power available. We used the 12V adapter to run the C-PAP, the inverter to run a Keurig Mini (once), and all of the other 12V stuff running directly from the batteries. After 2 nights out, we barely used 20% of available battery power. I never used the generator or the solar panels, and at the end of the trip we left confident that the new batteries provide enough power that we can use whatever resources we choose with zero concern of running low on juice. Plus, I am now confident that we could go boon-docking for a week and water would be our only concern, especially with the generator and solar panels as backup. In fact, I now know that the solar panels would easily keep up with day-to-day needs under reasonable circumstances.
These batteries are awesome!
