[A/S] temporary winterization?

[Chris Koehn <timberguides@xxxxxxxxx>]

All-
I have a question about winterizing. We'll be in Hot Springs Village AR 
for the holidays visiting my folks. We'll be using the Airstream as a 
bedroom during that time, but not for cooking or bathing. The weather 
is predicted to be cold for the next week there- nights as low as 15 
degrees. I've already had experience with freezing and splitting the 
city water supply pipe that runs along the frame on the outside on a 
cold night in Virginia, and I really don't want to damage any other 
plumbing. However, we'll be using the Airstream full time again as soon 
as we depart HSV in early January, so full winterization might not be 
needed.
Are there precautions I can take to insure the pipes remain thawed 
short of full winterization (bleeding all the lines and installing anti 
freeze)? We will be keeping the coach heated, which seems to keep some 
bath and kitchen plumbing in good shape.
Thanks as usual!
