Sometimes you need a little extra space to carry large items. Many Vanagon owners pile that sort of thing on roof racks. They even sell Rocket Boxes for extra storage space. This guy, however, has a rear bumper tow hitch that holds a bar to create a storage area to carry extra gear. I’m not sure what it’s called, but it’s slick.
Check out the profile of the Van. That storage area sticks out quite a bit, but it’s managable.
