Hi, a quick update from the OP.
First, thanks again for many helpful suggestions, and a few that seemed a little silly.
My goal is to keep things running through the night with no shore power. CPAP and residential fridge need to run all night without killing the batteries.
I don't intend to buy a larger gen, run the MH engine at night, or swap out my fridge for a propane unit.
Fortunately, I discovered that my inverter/converter/charger (on the MH) has a dip switch that lets you select charger amps at 55 amps (normal), or 15 amps. The little Yami will power the MH when the dip switch is set to 15 amps. So, I can power the fridge & CPAP most of the night and also put a small charge into the batteries. PERFECT!
