Actually what I have found useful to bring is a little sponge to mop up/scrape off all the frozen condensation on the inside of your tent. You scrape it all into a shove blade or pot lid when u wake up that way it isn't snowing in your tent when you are moving around inside getting ready to go. Thats a geeky tip.... but i highly recommend it. As for luxuries. Salsa and natcho chips in your base camp cache is killer..... Single malt scotch ain't too bad either Have phun!
