Saw these awesome cargo liners for the 3rd row 5th gens! They are only available in Canada for some reason. They should sell these in the states as well. You are able to purchase them from this canadian toyota dealership though. Many of us on the Facebook T4R group page have. Mine just arrived today!
These are much nicer than the liner that is available in states that you have to roll up when using the 3rd row seating or that shifts and slides around when the seats are down. And you can have either seat up or down and still have the liner intact and useful.
Install is with 3M type velcro for easy install and removal.
Heres the link if anyone is interested if this hasnt already been shared here. I tried to search but I only saw the other cargo liner for dogs.
