I'm 6'1" 170lbs, and on my last 6 month tour kept the same weight. (some fat did turn to muscle) My caloric needs are approximately 2500 base calories + 250 calories per 10 miles of riding. I eat my 2500 during two main meals and try to eat the rest as frequent snacks. 70% carbs. I'm vegetarian so I try to eat lots of pb, beans, whole wheat, dairy.

I wear glasses and carry spare contacts. Riding all day can dry contacts out, unless you also wear sunglasses. I was also worried about having clean hands for when I change contacts.

I use a bear keg as my handlebar bag, but I am a rarity. Know the alternative methods of critter deterrence/avoidance like not cooking were you sleep, various hanging methods, avoiding critter problem areas (like campgrounds) Check other sites for more camping tips.

Taking your bike to a bike shop and having them ship it will probably be the cheapest, easiest option.

If your tent has to be camo for you to remain unseen, you aren't finding good enough stealth spots. I tour with a bright white Tyvek tarp and rely on 1. Making sure that no one would be nearby to look for me and 2. Using cover/lay of the land to block the likely vantagepoints.

How dependent do you want to be on what food is immediately available on the route? When I toured the East coast I went no-stove; when I toured the Southwest, I brought a stove and used it frequently. If you plan on using wood as a fuel, use a real backpacking wood-fuel stove, not just campfires. Please don't make campfires at stealth camping spots.

There's nothing wrong with talking to yourself. Be worried though, if you start getting an answer.
