Hi, just bought a 2018 Limited today. Went from a 2005 Nissan Pathfinder. Nissan did an incredible job of removing ALL of the gaps when the two rows were folded flat. Ford not so good. In the Pathfinder I put a 5” thick custom cut foam pad for camping. There’s too many gaps in this Expy for that. Especially immediately behind the drivers and passengers seat. Aside from sliding in a sheet of plywood, has anyone figured out a good way to close the gaps?
