Abstract: Side rails can include a longitudinally extending rail track having support surfaces and a plurality of longitudinally extending linear grooves. A storage housing can provide storage tracks in alignment with the forward end of the rail tracks. In addition, a roll-up tonneau cover can include a plurality of slats pivotally connected together. Corresponding first and second sides of the slats can be supported above the grooves on a respective one of the support surfaces of the rail tracks. The slats can be movable along the support surfaces between a storage arrangement wherein the slats are supported by the storage tracks to provide access to the cargo box, and a deployed arrangement wherein the slats are supported by the support surfaces of the rail tracks to cover the cargo box.

Abstract: A latch can be movably mounted to each of the side rails for movement between an unlocked position and a locked position. A release actuator can be movably mounted to the rear header to extend adjacent both latches for movement between a non-release position and a release position. When the rear header is seated in the rear header seat and the release actuator is in the non-release position, each latch engages the rear header in the locked position to lock the rear header and side rails together. When the rear header is seated in the rear header seat and the release actuator is moved toward the release position, the release actuator engages both latches and moves the latches to the unlocked position to unlock the rear header from both of the side rails.

Abstract: A pump assembly includes a housing defining a working chamber, a water pump chamber and a waste pump chamber. A first diaphragm separates the water pump chamber and the working chamber. A second diaphragm separates the waste pump chamber and the working chamber. A common driver member interconnects the first diaphragm and the second diaphragm. Movement of the driven member to a first position creates a positive pressure in the water pump chamber and a negative pressure in the waste pump chamber. Movement of the driven member to a second position creates a negative pressure in the water pump chamber and a positive pressure in the waste pump chamber.

Abstract: A flush toilet assembly includes a bowl assembly defining a bowl and a base supporting the bowl assembly. One of the bowl assembly and the base may include a male coupling element and the other may include a cooperating female coupling element. A flush lever may be interconnected to the base for movement between first and second positions and may include a cam surface. A water valve may include a cam follower associated with the cam surface and may be moveable from a closed to an open position through cooperative engagement of the cam surface and cam follower in response to movement of the flush lever from the first to the second position. The base may integrally define a flush water path extending between an inlet port and an outlet port. The water valve may be disposed within a recess defined by the base which intersects the flush water path.
