I went with 1" blue styrofoam inside 1/2" MDO and the brown paper bag treatment for inside finish. Roof is luan then 1" foam then another luan. Seems nice and cozy but I haven't had a chance to use it too much yet. Just over the past few days I've been thinking more and more about the floor. I suspect I will put some 1" down there too.
