I've built a custom drawer storage system for the trunk of my 4Runner and the 4runner is being sold. It's designed to fit the third gen 4Runner model years 1996-2002. Everything is 3/4" ply and is VERY sturdy. The unit attaches through bolts to the body of the 4runner so it is secure incase of accident. It also comes with two extra extensions for the back seats and with that can turn it into a sleeping area. I'm 5'11" and fit. It's got two slide out drawers that slide out 22". Storage on either side and one in the back. The sub is a le wood marine enclosed sub with amp and all wiring back to the battery/ head unit. In the Orlando Florida area
