I live in the area of Florida that was hit by hurricane Charley. On my way home from work today my boss had me check on a genset that was recently installed by our company on a large house. When their area lost power it kicked in and did it's job-for 30 hours. It was a propane fueled unit and ran out of fuel on Sunday, leaving the homeowners in the dark again. It had a 125 gallon propane tank. My boss recommended geting a larger fuel tank. The homeowners still lost their food. How are you going to get propane fuel delivered on a Sunday after a hurricane? Diesel was available at the stations long after they sold out of gas.
