If I'm car camping with family I love my 2-burner Coleman stove attached to a 20 lb. propane tank. Nobody in my group will ever lack a warm meal or a hot drink on a cold day.

If I'm hiking to camp then my old external frame pack has a special place in my heart. It isn't for every adventure, but I pull it out when I need to haul weird or oversized loads for special occasions. I've carried bundles of firewood, cases of beer, family-size tents, and other foolish things that wouldn't work well with my more modern packs.

Edit: If I'm hiking and carrying normal stuff then I love my Lafuma down sleeping bag. It's wonderfully small and light while still being toasty warm.
