Have seen a few threads asking questions about bedrug fitting in 2019 DT with box. I ordered on Amazon, says it won’t fit but I would say it fits perfectly. I made no cuts or alterations( except at tie down points to slide through). Lines up everywhere it should. Hope this helps make a decision for those unsure. Bedrug is awesome. Only flaw is it makes a water tight seal impossible at tailgate with tonneau cover but it is really not a big deal. Water stays put in gate jam area.
