>>441185just did a weekend winter camping, although not in the mountains.
if you want to save yourself some energy(depending on your itinerary) you can get a pelican ice fishing sled from canadian tire for 40$ and slide your gear around. i strap one to my rucksack and ruck it around rough terrain.
you can obviously get a more expensive one since you look like a richfag, i believe the "viking" brand makes higher end ones.
