I just got the Gobi rack for my '12 JKU, and after installing it, I can say that I am impressed. From the minute you open the packaging, you can tell that details matter to the manufacturer of this rack. Someone mentioned, well thought out, and that it is. All interfaces are padded, and all the hardware included is stainless steel, they also use nylon lock washers, wear pads in many places to protect the vehicle. Everything down to some nice corner guards included on the rear just matches up perfectly. The finish is excellent, absolutely no flaws. The installation is straight forward, no drill, logical, and comes with very detailed instructions with figures. I jumped (literally) on top after it was installed and nothing budged except the Jeep's suspension. It's solid, and I'm 250lbs.
People mentioned other racks to me, mainly the Kongo Masters, saying it provided more capacity @ 500lbs of load carry capacity. However, that is the rating on the frame, and doesn't include the weight of the cage, which reduces that number. You will notice that the Gobi says 300lbs capacity, but that is on the rear section, and if you add the freedom panel insert section, you get an addition 150lbs on that section. Deductive reasoning should tell you that the frame of the Gobi can support at least 450lbs, based on that. With others, you may get the capacity at the frame, but the cages you buy may not actually support that weight. So, I would consider the Gobi a 500lb rack, and that's about as much weight as anyone should ever consider carrying on a roof rack.
