Super simple and stout storage platform for FJ80s. Made of 1/4" plate aluminum. Attaches using factory 3rd row seat mounts and two additional bolts. Easily removable. Can use either full or half platform if you need to use one of the third row seats. Has multiple attachment points to lash your gear down. Covered in crappy carpet right now, but you could replace that and it will look great.
$250 OBO (there is about $200 in aluminum in this)
