When we winter travel toward an above freezing destination we leave with our camper or 5th wheel winterized and leave it that way until we are in above freezing daytime conditions. We carry some drinking water in the truck cab in jugs. We run the furnace. We flush the toilet with RV antifreeze. We don't carry food that will freeze damage. We have warm blankies....
If you route home via the great plains you will travel in many days of winter weather. If you route home via Yukon,BC, and the west states you will have milder weather and lose winter sooner.
Sounds like an adventure...
