I purchased two of the 12.7ft racks. Assembly was easy with 1 person. I bought 16ft 2x4s and cut them down to the full length of the rack and screwed the racks down to them as you can see in the pictures for better stability. If no wood is in the rack and you move them around, the 3 separate racks screwed together are a little flimsy. This isn't an issue if you have wood in the rack as you won't be moving rack. One thing I would recommend, and this is why I gave a 4 star instead of 5 is after you stack your wood, the weight of the wood bows the middle of each rack section. You can see this in two of the pictures. I would recommend sticking a 2x4 in the middle of each section. I plan to do this after I've unloaded my firewood. Also when stacking the wood, try not to stack the wood against the walls so it leans on the sides but instead position the wood so the wood doesn't touch (put force) on the rack side walls.
