Pulled the roof rack off for some functional changes. I have loaded the bins on the back every trip think it is contributing to some sagging once fully loaded. I am moving my mounting points forward, my Max Trax to the back to better place weight towards the center. I am also adding a mesh flooring in place of the sheet metal flooring I had put in the back half. The metal was thick enough to hold weight, but thin enough it really grew and shrunk with temperature changes. Summer was fine as it stretched itself out. When cold, it pulled back some and would vibrate in certain conditions. I will make sure it has a wider 1/2" gap around the radius to eliminate the vibration. Did some grinding of some rusting spots and am painting it later today. Forgot how heavy that damn thing is!
