I have these and they are great. I don't think you are going to get the weight limit that you want, but I can get you to the width. I know it says for a Compass, but they work and they look good as I have them on my '22 Grand Cherokee L (with a sunroof). They sit a little lower than the factory one and the bars over hang the side of the rail and looks a little more sporty to me. Easier to tie off things with the edge of the bar sticking out.
