After so many years of putting stuff in the interior of this truck, (since 08/04) I found a little surprise that may have been engineered in, or wound up being there unintended. If you have a quad cab, with the fold out floor, put the long half of the seat up and leave the floor stowed. You'll fit a fast food/ coffee shop 4 drink holder perfectly in the indent in the center over the cup holders. I mean it fits perfect and snug.
