Well, I went ahead and winterized the water pipes, thinking at least if I can talk rest of family to go out one more time, ill just flush lines. Only took about 25 mins as it wasnt too bad. Thanks again for all help, this is a great site for info!
A couple hours at 32F is not going to cool down the water in the water tank or water heater enough to freeze it. The heavy wind make it cool down quicker but I don't believe it even got down to 32F in most parts of Illinois.
If your seriously worried about electric fan heaters get a baseboard or oil filled unit. I have an oil filled unit, and still will not leave it unattended. Neighbor was a fireman....I've heard it all about space heaters and I just prefer not to have me or my 'go up in a ball of flames in a second' MH become a statistic.
I fuel my own truck eat bacon and drive to work so I think I can live with the risk
