Recreational vehicle slide out system

A slide out compartment system comprising:

• a mobile dwelling assembly including an outer wall, a top wall and a bottom wall, said outer wall extending between said top and bottom walls, said outer wall having an opening extending therethrough;
• an extension being slidably mounted to said dwelling assembly and forming a covering for said opening, said extension including;
• an upper wall;
• a lower wall;
• an exterior wall extending between said upper and lower walls, said upper and lower walls being slidably coupled to said dwelling assembly to allow said exterior wall to move toward or away from said outer wall, said exterior wall forming a covering for said opening when said extension is in a stored position fully retracted into said dwelling assembly, said upper wall defining a roof and said lower wall a floor of a compartment formed by said extension when said extension is in a deployed position fully extending outwardly away from said dwelling assembly;
• a pair of lateral walls, each of said lateral walls including an upper edge, a lower edge, a first side edge and a second side edge, each of said lateral walls being hingedly coupled to one of a pair of lateral edges of said exterior wall adjacent to an associated one of said first side edges, said lateral walls being pivotable into a closed position extending between said exterior wall and said outer wall when said extension is in said extended position, said lateral walls being pivoted to a position approximately orientated parallel to said exterior wall when said extension is in said stored position to prevent said lateral walls from substantially extending into said mobile dwelling assembly;
• and
• each of said lateral edges of said exterior wall having a slot therein, each of said lateral walls being removably extended into one of said slots when said extension is in said stored position.
