I used this box to mount under my deck-over trailer. The box is light weight and very well constructed and also very well packaged. I ordered 4ea 24\" boxes and 2ea 36\" boxes and all of them arrived in perfect condition. These boxes worked great for me because they were available not just in 3 different lengths, but three different sizes. I went with the smallest size because it is still plenty big for my needs and they don't hang below my trailer so far that they would bottom out and hit the ground. I would absolutely buy them again.
