@tripledtools: Some folks said the magnets on their DieselDock were not holding right, so here’s a quick walk through on why. If your truck bed is aluminum or you have a thick spray in or drop in liner, the magnets can’t grab the metal underneath. On clean steel they hold strong, and you can always switch to screws or other mounting options if your setup needs it.
