The logic is, if you can survive dead of winter with your kit, the rest of the year will be a picnic with a backpack on.
Sort of. The dirty secret is that, as long as you stay with terrain that allows for pulling a sled, winter camping is way more luxurious. You can take more heavy tasty food, have a bigger cushier bedroll, and you can dig a central footwell into the snow that makes tent life downright civilized. The days are shorter so you sleep more. It's a good time for telling stories around the wood stove.
