I have a 2013 Model S with a panoramic sunroof and I cannot figure out whether I can still get a roof rack installed, but we need one for an upcoming trip (to put a box on). It looks like Tesla no longer sells or installs these—is that just because they don’t make the pano sunroof anymore, or because there are issues with them? Are there any current racks being manufactured and sold that I can install myself? I am not a car person so I’m not overly confident in my abilities but I can follow basic instructions or hire someone
