I bought this box because I also only had just under 10" to spare above the racks on my 06 Jeep Liberty. I mounted it and wife drove in slowly...I cleared garage door frame by 1/2" and was happy as a clam. Another nice thing is that box opens from both sides so it is easy to load/unload. I carry a small 3 step ladder in back when I go skiing!
