The Yakima Cargo Box I own is a RocketBox Pro 14. I used cables, pulleys, and a winch to hang it right on top of where I park my car. When I winch it down, it lands right on my car’s cross bars.
The box fits well on top of the opened garage door. You can see that and the winch on this pic:

This project was a lot of fun; it involved pulleys and a winch! I thought I’d share this in case someone’s looking for ideas.
