I had a lot of rocks and large logs in the back yard of my wooded lot I was trying to clear. I bought this so I didn't have to take things to the dump, just move them to a wooded part that I didn't plan on clearing and let nature take its course. I've had the trailer full with large rocks, and the tire pressure dropped drastically, but it hauled the load. The tires could be better, but they do the job. The tailgate piece doesn't attach, but just slides into guides. If you're hauling brush then it will probably bend and fall out. The good news is the tailgate is so thin you can bend it back. If you want something tough to haul stuff around in this is the thing to buy.
