winter camping for the first time... help!

[coralcrazed]

ok going camping in below zero temp for the first time... I sure could use some advice on do's and don'ts... what to do about the water hose during below zero temps at night? day? sewer lines? are there any precasions to take with onboard water supply? do you fill the water tank? drip the faucet to prevent freezing? pour anti-freeze in the sewer tank? will the onboard heat sorces be enough to keep the camper warm at night? do you reccomend bringing allong additional electric radiators/heat sources for supplement? is the 2730 insulated enough to keep the heat in and maintain a comfortable interior temprature? is there air infiltration through the flaps...? lots of questions. If you've been camping in the winter or traveled in your camper in cold months... I'd like to know tips/tricks/advice/warnings... thanks in advance.
