Abstract
A slide out room is glidingly supported from a main structure by a flexible tension member defining first and second lengths, each length trained about a set of rotatable support members carried by the main structure such that the tension member supports the room from the rotatable support members in both its extended and retracted positions. A tensioner connected to the tension member is used to adjust the tension in the tension member. A leveler carried by the room includes a longitudinal adjustment member that engages the tension member, whereby the room may be leveled relative to the main structure by adjusting the adjustment member.
