Abstract: A modular cab/sleeper/roof structural assembly for a truck-tractor vehicle according to the present invention provides greater manufacturing flexibility and unrestricted access between a cab/sleeper unit. The structural assembly includes a top-free cab unit having a front wall, opposing side walls, and a bottom portion. A top-free sleeper unit positioned behind the cab unit has a rear wall, opposing side walls, and a bottom portion. Fasteners couple the cab unit and the sleeper unit such that an upwardly opened carriage assembly is formed. A unitary roof member fixedly encloses the opened carriage assembly and forms an integral modular unit. The unitary roof member has a front portion connected to the front wall of the cab unit, a rear portion connected to the rear wall of the sleeper unit, and opposing side portions connected to the opposing side walls of the cab and sleeper units.

Abstract: The invention is a modular truck sleeper assembly that allows truck sleepers of various sizes and trim levels to be built on the same assembly line by pre-assembling the floor and sides and connecting them together during final assembly. A floor made up of a plurality of cross-members attached, with a predetermined distance between the cross-members, to a plurality of sills, with a first member of a foot/shoe combination attached to each of the cross-members' ends, is previously assembled and groomed with panels and cabinetry. A plurality of sides made up of a bottom stringer, a top stringer, and a plurality of risers attached, with the same predetermined distance between the risers, between the bottom stringer and the top stringer, with a second member of the foot/shoe combination attached to each of the riser ends, are also previously assembled and groomed with panels and cabinetry.
