Surprisingly, the bolt-on brackets were much thicker and heavier than I expected for the price. Was expecting something much flimsier. The 48 in. bunks are only 44 in. but worked fine for my use. Bunks aren't covered in carpet, more of a felt type material. Probably won't last long but will be easy enough to re-cover. Installation was straightforward but had to drill a couple of holes because I have diamond plate steps in front of and behind the trailer fenders.
