Abstract: A tire chock having an at least partially threaded rod; a first trunnion having an aperture therethrough that receives the rod; first and second locking members, one locking member being rotatably fixed relative to the rod, the other locking member being rotatably fixed relative to the first trunnion. A tire chock may alternatively have an at least partially threaded rod; an upper trunnion rotatably attached to the rod; a lower trunnion threadedly attached to the rod, the lower trunnion translating axially relative to the rod upon rotation of the rod relative to the lower trunnion; a pair of linkage arms, the pair of linkage arms forming an X-shape, each linkage arm being connected to the lower trunnion by a drive arm and being connected to the upper trunnion by a support arm, wherein, as the rod is rotated relative to the lower trunnion, the linkage arms expand or contract.

Abstract: A brake fluid flush machine comprises a used fluid tank, a new fluid tank, a manifold connectable to four secondary brake cylinders, a suction pump connecting the manifold to said used fluid tank for draining used brake fluid from said four secondary brake cylinders, a pressure pump connecting the new fluid tank to the master cylinder, and a processor. The processor is configured to control the fluid exchange by sequentially opening and closing valves that couple the four secondary brake cylinders with the suction pump, where the valves may be opened according to a user specified sequence.

Abstract: The present disclosure relates to a support system having a slideout room, a trailer frame assembly and a jack screw assembly to increase, decrease or level the vertical placement of the slideout room. The frame assembly has extendable support members connected to a plurality of jack screw assemblies with telescopic tubes to extend, decrease or level the vertical placement of the slideout room. The telescopic tubes have a mounting plate on one end that attaches to the slideout room and a mounting bracket on the other end that attaches to the extendable support members.

Abstract: A slideout room leveling device for supporting and leveling a slideout room floor of a recreation vehicle. The device may have a base mounted to a threshold of the trailer frame and a support arm that has a friction reducing member mounted to the support arm. A spring member may be mounted on the base to assist in supporting and leveling the slideout room floor. The support arm of the slideout room supporting and leveling device may remain in continuous contact with the floor of a slideout room during extension and retraction in order to support and level the slideout room.
