I never really fill the starboard to 1/2 full but the door bows a little on the port side. I think again the higher deck on the 13 up LSV reduces the pressure on the dividers. I didnt remove the carpet covered front spacer at the top on both sides of my lockers gives you a little more room. You just have to watch the edges of the top deck. I ran a sanding drum along the edges to get rid of the sharp edge. The 1/2 dividers bowed with the factory ballast. I've installed the flow havent tested it yet. I hope to not have to run quite as much weight.
