I have heard of too many winter time LP issues. Again, are you a hands on person? Are you going to go out there with a pan of hot water and try and get it running, or just put in a call for service?
Again, how long the power is going to be out is something that drives me crazy. A while back during the BIG ice storm, no one was repairing anything. It was later revealed that all the "HYDRO" guys had booked off hunting that week.
I would rather a little generator that can run for weeks (or longer) on a little Diesel, than a Big unit that will only run for a few days.
