Just remember if in a potential flood zone that propane tanks will float. A floating propane tank can cause quite a stir when it starts bumping into bridges, docks, etc...
I have a 16kW Generac, and last winter we had a power outage that lasted 4 days. During the 4 days I ran it about 75 hours and used about 75 gallons of propane so my average consumption rate was just 1gal/hr. I was really glad to have it.
