Plan sounds pretty well thought out except my experience says "ditto" to GraciesDad, Gruelens and Moxy. We went south to SPI in far south Texas after Christmas last year leaving from Syracuse, NY. Black Ice was a blast
. We thought we would get warm temps when we hit Arkansas
, Nope. Ended up we had temps below freezing all the way into Lake Charles, LA
. What a disappointment, but hey, we survived, had fun, learned a lot and will be a lot better prepared this year. Winter seems to come earlier every year, or is it that I am just getting older sooner
. I would not charge any water lines until I am certain temps are above freezing and will stay there until my destination. That is based on experience and please don't ask how much that cost. Anyway, I digress, go and enjoy. Please travel safe.
