Abstract: A truck cab having a rear compartment with walkway and bed. A tiltable cab of a tractor-trailer type of truck includes a driver's compartment and a rear compartment. A portion of the doghouse which extends substantially upward into the rear compartment is replaced by a horizontal floor forming a walkway between the side walls of the cab. The floor extends into the remaining portion of the doghouse forming a drawer receiving cavity with a horizontal seat cushion positioned atop the doghouse upon a slidably mounted tray. The tray is moveable forward over the walkway and a back cushion normally mounted to the rear vertical wall is removed therefrom and positioned horizontally adjacent the seat cushion forming a bed extending across the horizontal area of the rear compartment.
