Sounds like a good setup. It seems like you could also use it for getting clean power for sensitive electronics on the go. Solar power on a high quality inverter is probably pretty stable but I probably wouldn't want to run a laptop straight off a generator circuit.
I used to own a propane backup gen and I loved it. Quieter and cleaner than gasoline and you can stock up on tanks and store them for a long time. Plus propane is useful for so many other things.
