An environmentally controlled sleeper area of a vehicle that is contained within a bunk area (that is in turn adjacent to a cab area of the vehicle). The bunk area has an end wall and a pair of side walls extending generally perpendicular to the end wall. The side walls and the end wall encompass or surround three sides of a bed. Along the remaining open side of the bed, the vehicle operator can maneuver in and out of the bed. An extendible and retractable thermal barrier is provided along the remaining open side of the bed. The thermal barrier rises above the top surface of the bed and thermally separates the sleeping area from a remainder of the bunk area. An environmental control unit provides thermally conditioned air that becomes trapped between the back wall and thermal barrier by virtue of the thermal barrier.

The quick-connect coupler includes a spring-loaded member being biased by a spring toward a locked position to lock the quick-connect coupler to the pump inlet fitting and being movable to a release position to release the quick-connect coupler from the pump inlet fitting. The quick-connect feature conveniently allows the pump to be easily and quickly disconnected from the dispensing system for cleaning or replacement. rface and a second side surface, the first face and the second face being substantially parallel and having a curved profile, the first face having a concave surface and the second face having a convex surface, the first side surface being adjacent to the first face and the second face, the second side surface being adjacent to the first face and the second face, and a substantially longitudinal locking portion, the locking portion including a first end, a second end and a substantially triangular cross section, the triangular cross section forming a back face and two angled faces, the second end of the locking portion being positioned adjacent to the first end of the tang portion, the tang portion and the locking portion being substantially longitudinally aligned, the back face of the locking portion being substantially longitudinally aligned with an apex of the first surface of the tang portion, the intersection of the two angled faces projecting beyond an apex of the second surface of the tang portion; a bushing portion, further comprising, a substantially cylindrical shape with a first end, a second end and a central bore therethrough, a surface of the central bore including female threads throughout the length of the bushing portion, an external surface of the bushing portion including male threads throughout the length of the bushing portion, and at least one slot extending substantially longitudinally throughout the length of the bushing portion positioned on the external surface of the bushing portion, the slot having a bottom surface and two wall surfaces, the two wall surfaces being substantially parallel to each other and substantially perpendicular to the bottom surface, the depth of the slot being greater than the depth of the male threads on the external surface; the tang portion of the at least one key being positioned within the at least one slot toward the first end of the bushing portion, the edge between the first face and the first side surface of the tang portion and the edge between the first face and the second side surface of the tang portion being positioned in contact with the bottom surface of the slot in the bushing portion, the edge between the second face and the first side surface of the tang portion and the edge between the second face and the second side surface of the tang portion having an interference fit with the two walls within the slot of the bushing portion; the locking portion of the at least one key extending beyond the first end of the bushing portion; and the depth of the at least one slot of the bushing portion being sufficient that the apex of the second surface of the tang portion of the at least one key is positioned at a depth deeper than the inside diameter of the male threads on the external surface of the bushing portion and the intersection of the two angled faces of the locking portion of the at least one key is positioned at a depth shallower than the inside diameter of the male threads on the external surface of the bushing portion. 2. The threaded insert of claim 1, wherein the male threads on the external surface of the bushing portion are configured to mate with a threaded hole in a parent material. 3. The threaded insert of claim 1, wherein the female threads within the central bore of the bushing portion are configured to mate with a male threaded fastener. 4. The threaded insert of claim 1, wherein the at least one key comprises four keys, the four keys being positioned approximately ninety degrees apart from each other about the circumference of the bushing portion. 5. The threaded insert of claim 1, wherein: the first side surface of the tang portion of the at least one key is substantially perpendicular to a tangent along the first face of the tang portion at the intersection of the first side surface and the first face; and the second side surface of the tang portion of the at least one key is substantially perpendicular to a tangent along the
