i did a search but came up with fairly old threads. wondering if anyone has found a cargo liner option that they really like for behind the 3rd row? i have seen the tesla store liner for $130 but that looks to be rigid plastic and would have to be removed entirely when 3rd row seats are in use. on our mercedes GL, we have a product called canvasback that has a split between the two seats and is made of canvas and attaches to carpet with velcro. it allows you to leave it in place all the time, and it doesn't matter if 0, 1 or 2 third row seats are in use. has anyone come across one that they like and could share a review and/or photos? TIA!
