I also have a 2018 white F, three months old and 1835 miles so far, fuel economy average since Day 1 is 45.4 mpg. The sum total of changes from stock were a Throttle Tamer and I backed off 2 notches on the compression damping on the fork and 1/4 turn softer on the rear shock damping. Those tweaks made it a perfect all-arounder for me. It's my daily commuter and my weekend day-tripper.
One thing though, if you're intent on touring -- apparently not much thought was given to luggage accommodations on this bike from the factory. I'm sure you could make a bagger out of it somehow, I just wouldn't know exactly where to start.
