A method for manufacturing a bunk assembly for a transit vehicle is provided. The method includes forming an upper shell and forming a lower shell. The method further includes installing a frame between the upper shell and the lower shell and joining the upper shell and the lower shell together to form a support panel. The method further includes drilling a fill hole and a vent hole in the lower shell, the vent hole having a first diameter and filling the support panel with foam through the fill hole via the fill hole and such that air contained within the support assembly is vented through the vent hole. The method further includes redrilling the vent hole to a second diameter to form a mount hole, the second diameter being greater than the first diameter and mounting hardware to the support panel at the mounting hole.

Systems and methods are disclosed for providing a deployable fairing system to a tractor trailer. The deployable fairing system includes an actuator used to extend the deployable fairing from an unextended configuration to an extended configuration to occupy a portion of a gap area that exists between a tractor and an attached trailer. The deployable fairing includes deployable upper and/or lower horizontal assemblies that are pivotally coupled to a frame attached to the tractor/cab, and two side panels that are pivotally coupled to one or both of the upper and lower horizontal assemblies. The deployable upper and lower horizontal assemblies and the two side panels fold in on one another along multiple hinged axes in the unextended configuration, and extend rearward from the top and sides of the tractor in the extended configuration to cover a portion of the gap. The fairing may advantageously flair from front to the rear.

A truck cabin comprises a driver's seat, a bunk, and a frame, the frame comprising a rear structure delimiting the rear of the cabin along a longitudinal axis of the cabin. The bunk has the shape of a rectangular cuboid, with two parallel lateral faces, a front face, a rear face parallel to the front face, a lower face, and an upper face parallel to the lower face. The bunk is located between the driver's seat and the rear structure and extends along a transversal axis of the cabin, alongside the rear structure. The bunk is rotatable between a horizontal position, in which the upper face is horizontal and oriented upwardly, and a vertical position, in which the upper face is vertical. In the vertical position, the lower face of the bunk is oriented towards the rear structure and the upper face is oriented towards the driver's seat.

A bracket for connecting a cabin to a chassis of a heavy-duty vehicle, wherein the bracket comprises a main plate having a cabin attachment portion for connecting to the cabin and a chassis attachment portion for connecting to the chassis, wherein the main plate of the bracket comprises an embossment which is embossed perpendicularly to the main plate, which is located between the cabin attachment portion and the chassis attachment portion of the main plate, and which extends along an embossment line from or proximate from a rear edge of the bracket, towards a front edge of the bracket. The invention also provides for a heavy-duty vehicle equipped with such bracket for connecting a cabin to a chassis.
