>>2661721Hot tent with a wood burner stove, a decent sleeping bag and a good sleeping pad, a cot to lift yourself off the cold ground, a battery powered lantern to light up the tent and a CO detector to make sure you will wake up in the morning. The wood burner stove will keep your tent both dry and warm, allows you to dry clothes in the tent and you can cook on top of it. Anyways I would recommend getting an additional camping stove for the moments when you need to cook without the wood burner stove.
Anyways, the best option would be to not stay in the tent for the winter. Good luck and have fun, OP.
