I've got a 2019 Tahoe LT with bucket seats on the 2nd row, and I generally fold them down and put down a waterproof liner for hunting and fishing that covers the entire back cargo space. However, when I fold down the bucket seats there is a fairly large open space between them that is covered by the liner, but I can't put anything over that space as there is no support underneath. I would like to know if there is something on the market that will fit into and fill that space and make it level with the folded down seats effectively giving me a full width flat support space, similar to what I would get if I had a full width 2nd row bench seat. I suppose I could swap out the bucket seats for a bench seat but would prefer a simpler option instead. Thanks.
