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.
