If its just for one person you dont need all that crap.
I sleep comfy in in the back of my new 4runner with the seat folded down and I'm 6'2". Still plenty of room for all my gear.
I also have one of those trailer hitch-mounted cargo carriers that I can put more stuff on if I need too. Climbing up and down to put shit on a roof rack is tedious and kills your gas mileage.
Pic is my inaugural trip with the 4runner on the White Rim Road last month
