For my upcoming, and first, tour I replaced my Whisperlite with a Dragonfly. I love to cook so the option to simmer is great considering you can only eat oatmeal and ramen so many days in a row. I got a basic water filter so that I have the option to go off the beaten path. I'm planning on getting a full sized laptop and an external hard drive since I see myself doing a lot of writing and posting photos and videos. Solar panel with built in battery. Definitely spare tubes and tire and a few more tools. Greater variety of clothing, maybe with less of each type to save on weight, for a variety of weather. Bike computer to help with navigation. Reflective gear for road and night riding. Extra nuts, bolts, zip ties, duct tape. Ointment for saddle sores and baby wipes for swamp ass. Hiking boots and sandles. Note book for writing. Spices. etc........
