Abstract: A water filter adapter including a manifold defining an inlet port configured to couple with an output of a water filter module and an outlet port configured to couple with an input connection of a system, for example a water tank of an RV or boat. The water filter adapter further includes a shutoff valve assembly positioned between the inlet port and the outlet port for controlling the flow of water at the input connection of the system rather than an external water source, such as campsite hook-ups or marina connections. In a preferred embodiment the outlet port is offset about ninety degrees from the inlet port to minimize the flow path post-filtration as much as possible while still facilitating a secure connection between the water filter adapter and the input connection of the system and between the water filter adapter and the water filter module.

Abstract: Systems and methods for a hose extension handle system including a tubular grip with distinct first and second ends, a battery carrier within the first end's cavity to hold a battery, and an engageable actuator on the first end's outer surface that is electrically connected to the battery. From the second end of the grip extends a housing including a light source, also connected to the battery and actuator. An upper strap with two extending arms and a lower strap that can be attached to these arms may be configured to secure around a hose. The light source within the housing may be aimed to illuminate the inside of the hose.

Abstract: Shock absorption assemblies are provided. A shock absorption assembly includes an air shock that has a valve body. An air spring tube defines an air spring chamber. A piston rod extends through the air spring chamber to an oil piston head. An air piston head movably coupled to the piston rod. An oil damper tube is coupled to the piston head and is movable relative to the piston rod and the air spring tube. The shock absorption assembly further includes a mechanical spring disposed radially outward from, and that annularly surrounds, at least a portion of the air shock.

Abstract: An adapter for facilitating an easy and secure connection between a sewage drainpipe and a sewage disposal inlet. The adapter includes a tubular member, at least one connection lug, a ring, and at least one flange. The tubular member forms a channel defining an inlet and an outlet, the outlet insertable into the sewage disposal site inlet. At least one flange extends from an outer surface of the tubular member to increase an outer circumference of the tubular member to allow the adapter to facilitate a rapid and secure frictional connection with the sewage disposal site inlet. The flanges are configured to form a stepped configuration so the adapter may securely fit into a variety of disposal site inlet sizes. The ring, typically disposed above the flanges, includes a threaded portion, and is configured to thread onto a predetermined sewage disposal site inlet size to form a substantially leak-free seal.

Abstract: A leveling block set with a handle, leveling blocks, and a receiver for leveling a large vehicle like a camper or trailer. Each leveling block has a top surface, sidewall, bottom surface, and a void defined by the sidewall and bottom surface. An opening in the top surface creates a channel that accepts and retains a portion of the receiver and the handle. The receiver has a base and shank with a passageway forming a second engagement member. The handle has a grip and shaft with a first engagement member. The shaft can be inserted through the channel to mechanically engage with the second engagement member of the receiver. The receiver is secured in the channel by two shoulders formed in the channel. If the receiver is lost or damaged, a replacement can be inserted without replacing the leveling blocks.
