I own the large cargo box with lights. I purchased it sometime in March and have used it on the back of my RV. It is fantastic. Has enough room for all my stuff and adds a degree of safety when traveling due to the lights on the box. This product is tops and I would recommend it to anyone. I recently purchased the cargo box cover as the RV has gone into storage and the protective cover keeps it clean. It just seemed like the perfect protection for the cargo box. It fits perfectly and made to last. I expect it to be used year after year. Again, I would not hesitate to reccomend these fine products or any other of the companies products.
