Minnesota Cold

The weather turned from very nice to very cold in a matter of hours.  We have to go into freezing mode with the motorhome which means putting water into our water tank and disconnecting the hose.  Also means using our propane furnaces as the heat pumps only work down to 40 degrees.  We can do it and stay plenty warm.  It would help it the wind would die down and the sun would shine.  It is Minnesota in October, what can we expect!  Northern MN is getting snow!!!!!
