my buddy had a setup like that in his s10. pretty cool but it was a little cramped height wise for me. I think his rack was up way to high and could have been lower.
for wasatchman either one is a good buy, but with small trucks, you have to have weight over the rear tires, snow tires isnt enough, in my experience. subies are nice, but you cant sleep in there with your gear, unless you have ski rack. i camped out once, kinda nice actually perfect length and my penny stove kept it nice and warm. im 6'1" 195 in a 03 forester. the outbacks are longer.
