This is a fast, competent, safe, durable, intuitive and comfortable bike designed to do exactly what you asked.
It is about $700 or so, which is a real bargain for a long range touring bike.
It will never require derailer adjustment. It will not require brake adjustment. And, it will last an incredibly long time with very little maintenance ever required.
