I took my measuring tape to the dealer because I care how long and wide the cargo area is. I do a fair amount of car camping and would like an air mattress to fit. My '02 4Runner it
was a bit cramped on the width, but the lenght was fine. Attached are some pictures of the measurements in case others care about these dimensions. I didn't measure the height because it is plenty for my purpose. The measurement over the headrests is starts back at the closed rear hatch. A 6' long matress is an easy fit. There are two width measurements because I was trying out the iPhone measuring tool which was surprisingly accurate. I also took a diagonal measurement.
