A low-cost, compact room slideout assembly is provided for driving a sliding element, such as a floor, and comprises at least one motor having a motor output pinion rotatable about a first axis, a drive screw operatively connected to the motor output and rotatable about the first axis, and a driving member, such an elongate ram adapted to be attached to the sliding element. The ram travels along the first axis between extended and retracted positions in response to rotation of the motor output shaft. Preferably operatively connected between the motor output shaft and the drive screw is a speed reducing gearbox with an output shaft rotatable about the first axis, and a 90 degree gearbox operatively connected to the drive screw and rotatable about the first axis. The 90 degree gearbox preferably also has a second output member which is rotatable about a second axis perpendicular to the first axis. The 90 degree gearbox can comprise a series of bevel gears. In certain preferred embodiments a pair of screws and a pair of corresponding rams may be employed, with a cross shaft connecting the first 90 degree gearbox to a second 90 degree gearbox.

A gooseneck trailer coupler is disclosed which secures a first structure such as a towing vehicle to a second structure such as a trailer. The coupler is provided with a mounting element extending from the first structure, a chuck having a top end and a base at a bottom end opposite the top end, with the chuck attached to the mounting element at the top end and adapted to receive a ball mounted to the second structure. A locking assembly is adapted to releasably secure the ball and the chuck, and comprises a ring gear mounted around the chuck and movable from a locking position where the chuck is secured with the ball and an unlocking position where the chuck is unlocked from the ball, wherein the ring gear translates from the base toward the top end of the chuck as the ring gear moves from the locking position to the unlocking position. The locking assembly can also comprise at least one jaw mounted in the chuck for engaging the ball when the ring gear is in the locked position. A novel release lever assembly is also disclosed which moves the ring gear.
