This is a great storage box for under the door where the steps have been changed out. I watched videos of the competitor's product, that is probably the same, and everything seems to match. This unit came with all the hardware and brackets, just like the competitor's product.PROS: Strong metal with power coating, very nice. Fills the space under that stairs and is very useful. Arrived in cardboard box with no dents or scratches. included all the hardware with 2 keys (just like the Mor-expensive brand).CONS: Do not use a razor knife to cut the tape of the packaging. My fault, but now I have a fine line across most of the front surface, argh. There was no warning and backup piece of cardboard inside to protect. On the Amazon site I did not see any instructions on mounting nor did it say that all the hardware and metal brackets were included, that would help other buyers, I took a chance on it. Also in the directions there is information on the "space between the mounting brackets" which is 27" to 28", that should be in the selling information on Amazon. This product is not waterproof, just like the Mor-expensive product. I used self-stick 1/4" thick foam around the inside of the top and sides of the lid/door in order to keep some of the dust and water out. This way it can still drain if needed under the lid/door and prevent rattling.I am totally happy with this product, except for my mess up with the knife. If you find and watch the video online of installing the Mor-expensive storage box, it is exactly the way you would mount this storage box. I recommend this and you wil save quite a bit of $$$. Happy RVing. Dave
