I bought a new 18ft aluminum utility trailer in June 2016 to mainly haul restored John Deere lawn tractors to shows and of course use it for other hauling also. I quickly found out I needed a tool storage box that could be mounted on the tongue for all the tie downs, jack and handle, dolly wheel, lug wrench, breakaway emergency trailer brakes battery and all the other things that's needed when traveling with a trailer. I ordered this box from Amazon because the dimensions seemed to be such that it would fit the trailer tongue very well. When it arrive and had the chance to install it, the tongue fit was perfect. The only downside is that I wished it had been made about a 1/16th inch thicker, it does seem to be a bit "light weight" as far as thickness. I've only had it on for about 3 months now, so time will tell if it's built for long life. I gave it a 4 star only because I think it needs to be a tad heavier in construction.
