Advice needed from coldweather folk.

Hey all, I am from the "it's a dry heat state" and am looking for a little advice for this next weekend. I am a big fan of the 115 degree temps that we have down here and am not a big traveler to the colder parts during the winter months (maybe a 2 hour trip to see snow then back home quickly). So my plan for this weekend may be a bust if you all think it's a bad idea. My mother is having her 70th birthday at a cabin up north in Happy Jack because it is the only time we can all get together at the same time and same place. The cabin is about 1200 sq ft and there are 26 of us that she is directly responsible for so it's gonna be cramped. My plan was to take the "Galactica" up for me and the boys to sleep in (probably 6 of us). The weather currently is mid 50's during day and mid teens at night. If I have a space heater going on the inside for the whole time should I worry about the freezing in my pipes and drains, they should already be pretty much empty but don't know about residual water. What is the main concern for driving in the cold weather or should I just leave her home and be up close and personal with the familia?
