First Winter Trip South - Pls Help Us Avoid Future Divorce

Try to leave when you have a good weather forecast for three days.
How far you need to go before dewinterizing depends on the winter, possibly NM or AZ.
We go south during the winter and we take bottled water to drink,cook and make coffee. Also have some gallon jugs(plastic)of water that we carry in the shower to flush the toilet. We're in MI so usually at end of second day it's warm enough theres no problem.
You might want to avoid taking any canned goods and just buy some when you get to warmth,
