First cold weather trip... Any advice?

Take your chains. I would not trust the forecast to get it right on Snow VS Rain up there. It is snowing now in Red River, I guess you are going skiing.

Keep a roof vent open an inch or so to help alleviate condensation build up. Use electric space heaters if you have power available. If it gets and stays below freezing I put a 60 watt light in the docking station bay. Make sure you have enough propane.

Have fun, we love to camp in the cold.

We always use the water from the FW Tank which avoids the possibility of freezing inlet hose. Some campgrounds charge the camper for any damage done to their water set up caused by the supply hose freezing.

Depending on the insulation of your unit, if you are worried about waterlines at night, open the doors of any cabinets that have water lines running through them. Disconnect the fresh water hose at night to prevent any problems there.
If you don't have thermal windows, crack a vent or window slightly to prevent a lot of condensation on the inside of windows or other surfaces. If hooked up to full hook-ups and depending on campground policy, use an electric heater to save propane costs....if that concerns you.

Have a great trip!

Stay home or head further south. :)
