Abstract: A leveling system includes a plurality of leveling blocks for leveling a relatively large vehicle and a handle for securing the plurality of leveling blocks together for convenient storage and transport of the leveling blocks without a container. Each leveling block includes a pattern of protrusions that extend upwardly from a top surface and a pattern of recesses formed in a bottom surface. Each leveling block has an opening formed therethrough and at least one of the openings is provided with an internal thread. The handle includes an extensible and retractable portion adjacent a proximate end thereof and an external thread at a longitudinal opposite distal end thereof. The handle is guided through the openings of the plurality of leveling blocks and the external thread engages the internal thread provided on the at least one opening to secure the leveling blocks together.

Abstract: A swivel coupling is provided for a waste disposal system having a first waste disposal component and a second waste disposal component. The swivel coupling comprises a first coupling portion having a first end and a second end, the second end being configured for connection to the first waste disposal component, and a second coupling portion having a third end and a fourth end, the fourth end being configured for connection to the second waste disposal component. The first end is rotatably connected to the third end such that when the second end is connected to the first waste disposal component and the fourth end is connected to the second waste disposal component, the first and second coupling portions are rotatable relative to one other.

Abstract: A flow thru telescoping handle for use with brush heads and other tools includes a telescoping handle having a tear-drop shaped cross section to increase the strength and improve its functioning capabilities. A spring loaded tension pin is mounted along the bottom of the outer section of the handle which is operated by finger pressure to engage and release it from the inner handle section. A method for adjusting the length of the telescoping handle is also described using the tension pin.

Abstract: A monolithic trailer hitch including a rack defining a plurality of apertures positioned in a recessed channel and integrally formed with a perpendicularly extending arm defining a cavity and a hollow with an end formed from a pair of opposingly biased faces. A brace is connected between the arm and the rack for structural support. The cavity is the larger of the two openings and is positioned more proximal the rack while the hollow is smaller and positioned more distal the rack, near an aperture configured to receive a fastener to secure the shank to a receiver and a tow vehicle.
