Good choice on the Honda. They are pricey, but pretty small, and much quieter than many gens. As for the gas storage, go to an RV supply store, or probably even the automotive section in Wally World, and get a bottle of Sta-bil , you put some (directions on the bottle) into your gas can and it will store for a long long time. And be sure to chain that Honda to a tree or something. I am sure you heard during the outage of gens walking away from their owners...
