Howdy Ryan, that sounds like a really awesome trip - Sicily must be lovely to cycle around. If you need any advice about kit, touring, bikes or anything along those lines, you're in the right place.
And Jags: save it for shavenlegsroadiebikeworldforum.com (or similar). ;-) Mountain bikes are wonderfully versatile - all the touring I've done has been on mountain bikes (yup, I consider my Raven Nomad a mountain bike).
