I have always loved backpacking, so why not combine that with bike touring and go BikePacking?

My dream touring bike would be a vintage model like a Peugeot PX 10 with sick parts. Zipping around on a real gem of a bike like a PX 10 would be so gratifying. I'm torn between that and buying a cyclocross bike. I like the idea of cyclocross becase when I do go touring, I can see myself succumbing to the urge to get on some dirt/gravel roads.

What do you experts/veterans recommend?
