Didn't find too many posts on roof top cargo boxes or similar but I recently got one and here are some photos. The cross bars are Honda OEM and the box is the Yakima Rocket Box 12. Install was a breeze and no problem so far. Our baby stroller takes up so much space in the trunk that there's not much room left. The box provides a lot of additional space plus, it provides extra security (sure a thief could easily crack open the lock with rudimentary tools....but then it we're back to being no safer than keeping things in the car). The thing I have to get used to now is being mindful of height clearance signs when entering garages. The box is 16" tall but that's sitting on top of the cross bars so I don't know what the total overall height of the vehicle is now. However, I can fit under my work garage's clearance bar with a couple of inches to spare, which is marked at 7'2"
