To keep the thread on topic - I'll note that the Cross Check is a fine bike for whatever you want to do. Other than making sure you have low enough gears for an uphill finish at the end of a day while fully loaded, you're probably in great shape for road touring. Unless you're wealthy, I'd save the money you'd spend on a new bike for some treats on the road.
As noted elsewhere, I'm down to 2 bikes - a junker single speed for around townand a 20+ y-old karate monkey with 3 sets of wheels and 3 forks (one suspended) that I have used for everything fron mountain biking, bike packing the great divide, road touring, and relatively fast, unloaded centuries.
As regards the devolution to discussion of the tern bikepacking - it's all semantics and the arguments sound familiar to those of us who backpacked heavy loads on stable frame packs (think racks on the bike) or climbed with softer and usually lighter packs for climbing. Comments above seem to reflect the fact that bikepacking with soft packs, in-line with the bike, and relatively aerodynamic, fit more with multi-day self-supported racing and less with long comfortable touring. Soft, light packs used for touring limit the weight one can carry. I suggest, to borrow a motorcycling term, we refer to these lighter, faster tourers as "sport tourers" - no matter how they carry the load. Any bike plus gear under 45 pounds (20 kg) would likley fit the bill. I'll start a new thread with this thought.
