Wow that is an impressive list I would like to see your packing skills to get it in. You can probably pack two weeks worth of luggage in the trunk like tetris haha. All jokes aside there's nothin like peace of mind, and whatever it takes is well worth it! I live in an area with heavy snowfall and make trips to go skiing several times a year. Yet I just have a winter coat in the trunk and maybe some gloves, almost always have a lighter...if that's even useful haha your like trying to compete with bear grylls! I tend to use that area of my x5 to bring a box or two of cubans back from canada eh! Ps breitling emergency watches rock, I have a couple breitlings myself, the emergency would def be right up your alley!
