Many years ago I did three long trips. Nearly 4 months, 7 weeks and 6 weeks respectively. The third trip ended in CO, where I met up with a woman I was dating. After her internship at Mesa Verde was over we did some car camping. Lots of stuff I didn't have when touring. Stuff like a lantern, cooler, board games and a second stove. I found the clutter hard to deal with, and what you needed at the moment always seemed to bbe burried under everything else in the trunk.
