Transportable living quarters for a main frame for supporting structure defining a main living area and a slide out room assembly being slidable relative to said structure between a retracted position retracted within the main living area and an extended position extended from the main living area to provide an auxiliary living area, said structure including a main floor supported by said frame, said slide out room including a slide out room floor movable from a raised position sliding over said main floor as said slide out room slides between the extended and retracted positions to a lowered position vertically displaced relative to the raised position and substantially flush with the main floor as the slide out room moves into the extended position and movable from the lowered to the raised position as the slide out room is moved from the extended position, and an extendable support member mounted on said main frame and connected to said slide out room for supporting the slide out room as the slide out room moves between the retracted and the extended position, the weight of the slide out room being transferrable from said main floor to said extendable support member as said slide out room is moved toward said extended position, said extendable support member being adapted to deflect in response to said weight transfer by a predetermined amount being substantially equal to the vertical displacement of the room floor to permit said slide out room floor to move to said lowered position, where said slide out room floor and said main floor are substantially flush.
