Generator Gas Usage, AC, and Battery Charging
It seems the Yamaha and Honda 2000 WATT Generators have the lowest fuel consumption. I have read these generators run about 8-10 hours on one gallon of fuel. Have owners of these generators found ...

Yes, charge rate from generator can vary. I would suggest that you checked that you have a nice 3 stage converter installed to charge your batteries. If not look into a progressive dynamics unit 45 amp or greater and ensure it is set up for 3 stage charging with the charge wizard. My Honda 2000 can run my roof ac but it is a small unit. Not sure of the BTUs, maybe 11000. The Honda is great because it will indeed run for 8 hours, and its rpm will go down as the current demand decreases saving you noise and fuel.
Charge rate to the batteries is highly dependant on these things: battery state of charge, size and length of wire to the converter, and converter amperage output. A Honda 2000 will in fact be able to run a quality 80 amp converter to charge your batteries at 80 amps, provided there is 4 gauge wire to the batteries that is short in length, and if you have enough batteries and low enough state of charge to accept this current. If you only have 1 or 2 batteries, there is no point in a converter with an output higher than 50 amps. This is because the batteries even when heavily discharged wont accept 50 amps for more than a few minutes anyway.
So, in short you may be able to run your roof ac with the Honda 2000 provided that the converter has already charged your batteries most of the way, the fridge is on propane, and no one else is using an appliance at the same time.
