We have now used this luggage rack on two trips on our 4' x 7' cargo trailer. We believe the National Forest campground is quite safe when traveling through Yellowstone National Park. I like it because it's a deterrent to random thieves. A thief with an acetylene torch can easily "cut" it off, but most casual thieves come unprepared. It serves our purpose very well, shipping was fast and the boot met our expectations.
