Do you expect to be able to purchase and/or draw from stored gasoline during an outage?
You may want to decide how much you value the option to run on Propane/Natural Gas - especially if you already use one of these fuels at the house.
This would be valuable during a large regional outage where gas stations can't pump and those with generators can't get fuel. This happened to us during hurricanes Sandy, and Irene.
I like the option to run on propane, a dual fuel unit would be perfect. I have quite a few propane tanks since I have a gas grill, camper, and an offroad truck that runs on forklift tanks. Plus propane can be stored for long periods without going bad. It can also be filled when there is no power.
