I went with the WeatherTech bed tray, Ford was out of stock. All my previous trucks were used as work trucks and the boxes were beat up pretty good. I never had a total bed liner, drop in or spray on, and I never felt the side walls of the truck needed protection. A bed mat is all I have ever used and that seems to work for me. I won't be dumping bucket loads of sand or dirt in the bed of this truck anyway but the tray keeps things from sliding around.
