The fact is, real touring, is hard to do. Set your sights to 2-3 day trips, get a bike that can carry enough stuff, and have at it. A dedicated touring bike, is like a dedicated race bike. Works great for the intended purpose, but everything else is a compromise. If you decide to go for it in the future, either get a bigger bike, or make the one you have, work. Keep it fun. It's not a car. You can't carry enough to get by, and when the weather turns to crap, you still have to get home.
