Need some advice with cold weather

I lived in Dallas for 4 years .. I will never forget the Christmas week we had in 1988 when the temps went to -5 degrees for 5 days! (actual air temps..not wind chill!) This was our first winter in Texas and we could not believe how cold it was! Everyone's pool froze up and we had thousands of $ in insurance claims! Welcome to Texas! The point is, there is NO way to predict weather in North Texas in winter-- 70 degrees one day-- 20 degrees the next-- or colder!! Black Ice is frequent-- Forget driving on it with a car let alone a trailer! I would not take a chance that late in the year and get a hotel! Even if you winterize, it will not be fun to bring bottled water and have to use public toilets or someone'
s bathroom you are staying with. Not worth the risk in that area in December!
