The AT Habitat Sink/Storage Cabinet Comes in two designs. The first includes a built in sink that you can connect to your own water supply and water pump. The second design does not come with a sink and is built with storage shelves from top to bottom in both the left and right section.
In the Tacoma version, the lower section has a front panel that is the same height as the wheel wells with a removable shelf above. This is a great location for utility items such as water pumps and other items you do not need during a normal outing.
