First of all, welcome to the forum.

Do I understand correctly that:
1. You do not have shore power available
2. You ran the generator instead of connecting to shore power
3. You used a charger powered by the generator because you suspected your converter was not working properly.

How ling did your batteries last after this test?

The others are correct; the batteries installed by the dealer (the factory does not install batteries) are probably junk and need to go. I installed 3 12V 100AH AGM batteries to give me a capacity 300AH. I elected to stay with the 12V batteries because there is only room in my battery compartment to install three batteries, so, at the most, I could have only installed two 6V batteries (have to be in pairs) for a total of about 200AH.

The furnace blower is probably the biggest 12V device on your trailer. When we boondock, I don't run it. My last unit had a catalytic heater; on my list for the Montana.

I agree with the statement about the residential refrigerator; it's not for those of us that camp a lot off the grid.
