Everyone has an opinion, just like everyone has done some bonehead things we probably shouldn’t have done or continue to do.
My first three winter camping trips a full of bonehead stories, some really really stupid to the point of dangerous Couple tips to save some headache.
Heat – I’m firmly in the camp of not using propane while sleeping, too risky for me. It’s amazing what a treat that is in the morning to fire it up, make a hot drink, and some breakfast.
Sleeping pads: Tegg’s right and took me until my third trip to learn this one. Even if using a cot, you need this insulation underneath you for conduction cooling.
Sleeping bag(s): one really good one or two decent ones. Was at an outdoor expo where the advice was to use an outer synthetic bag and inner down. This way you could do better at managing moisture and not need to buy a -20 super specialty bag.
X2 with Tegg’s tips other tips. As for the bivy sac, it’s optional for me. Most of the time I leave mine at home.
Vented wood stove – super awesome but kills the idea of being mobile at all. You won’t move camp once this is setup. A hub portable you might pack it up if you want to go sit on different structure.
