Drove around a bit, and was able to get the generator started. Hoping the house batteries will now charge up. Not sure I have the expertise to do too much more.
I noticed when storing the power cord that there were some ants in & around the storage bays. Sprayed a bit, and cleaned off the pollen and debris that had accumulated on windshield, and saw a few ants there, too. None on the inside (yet), but I wonder if some could have travelled along the power cord and caused a problem that prevented the batteries from charging while I was plugged in?
I should have fairly mild weather on my short trip, so I won't need a lot of A/C, and I think I can get by with just running the generator to make coffee and use the microwave a bit, while cooking outside on the grill. Might have to run the refrigerator on propane, too, but I think I can get by, and then have the RT dealer check it out after I return, although any additional input here is welcomed.
