I have the Ford Bed Divider. Added some tie down points from Amazon. Can pretty much secure anything back there with bungee cord or strap. Divider comes out easy when I need the full bed.
I just had this happen to me. We were on the interstate and had been cruising along for about an hour. Had to slow down for a crash and as we were coming to a stop here was a loud clunk that shuddered through the truck. Truck was in 4A as there was ice on the road. I also happen a few times in...
UPDATE - Finally got my truck back from the body shop. Happy to put this issue behind me. Thankfully it was only the box that needed work. I will definitely be looking the next truck over really well before driving off the lot. Lesson learned.
We did check all of that at the dealer yesterday. I have been following your unfortunate situation you have with your truck. Hopefully it is all corrected when you get it back!
