2019 XLT FX4
Ha Ha. Okay, so I went to go check my FX4 to see about this gap.. I never knew I even had a sliding door. I just thought maybe the cover didn't come on the XLT versions and only the higher trim levels. Turns out, I do have the door, but always leave it opened because of the USB cable and/or charging pad. And of course, the handle for the door slides back into that gap if the door is open.
