Abstract: A portable tank for handling recreational vehicle liquid waste comprising a molded receptacle of synthetic plastic material having wheels, including a caster wheel. The receptacle is provided with an inlet port for receiving liquid waste, and an outlet port defined in a side of the receptacle is opened and closed by a gate valve permitting the receptacle to be easily emptied.

Abstract: The invention pertains to electrically operated levelers and stabilizers for vehicles, particularly recreational vehicles, wherein a reversible electric motor extends and retracts telescoping members mounted to the vehicle by a linkage system. Operation of the linkage system through a linkage and slot arrangement automatically pivots the stabilizer to a horizontal storage position and lowers the stabilizer to an operative position during extension of the telescoping members. The links are locked by an over-center relationship when the stabilizer is extended, and automatically unlock from the over-center relationship when the stabilizer members are retracted and raised. A foot at the outer end of the stabilizer automatically pivots between storage and operative positions.

Abstract: A modular room extender for recreational vehicles, modular homes and the like utilizing a pair of axially displaceable slide rods having outer ends attached to the extendible room. The slide rods are mounted within a bracket which includes spaced parallel guides wherein the bracket slide rods and guides define a modular unit which may be installed as a complete assembly. The slide rod's inner ends are free and not connected to other structure, and a reversible electric motor operates a gear and rack system for extending and retracting the slide rods. A stamped metal rack of economical construction is attached to each slide rod.

Abstract: An above-the-floor freestanding drive-through vehicular hydraulic lift in which a pair of laterally-spaced cylindrical columns enclose hydraulic elevating mechanisms and each column supports a vertically displaceable lifting assembly for engaging a vehicle in synchronization with an adjacent vertically displaceable lifting assembly on an adjacent column for supporting and elevating a vehicle to selected working locations. A lifting a lowering assembly is provided with an automatic locking and safety mechanism for sensing obstructions to which the supporting and elevating mechanism may be subjected in elevated and lower a vehicle supported on the hydraulic lift.

Abstract: A combination satellite television signal receiving antenna and a UHF/VHF antenna, particularly suitable for use with recreational vehicles. The satellite antenna is mounted for both horizontal and vertical adjustment having a circular periphery and the UHF/VHF dipole antenna is attached thereto and is of an arcuate configuration defining a portion of a circle concentric to the satellite receiving antenna dish configuration. The television and UHF/VHF antenna are mounted for simultaneous adjustment.
