Used the Yakima Rocket Box Pro Rooftop Cargo Box 14 cubic ft for one trip. Returned it and bought a Yakima Sky box 21 cubic ft… I might be able to fit my Subaru Outback in it…. Never can have to much storage.
Wow, I can't imagine how you got the 21 to fit on an Outback! I just mounted the 16s to my Outback and even mounted as far forward as possible, it BARELY fits without hitting the trunk spoiler:
SO MUCH space in there though, I love the thing.
