Expandable mechanical structure for mobile living units

A recreational vehicle, comprising:

• a main body having a width less than 102 inches and a length less than 35 feet;
• a first side expansion structure operable to extend from a first side of the main body, the first side expansion structure increasing an interior living area of the main body by 50 to 120 percent;
• a rear expansion structure operable to extend from a rear of the main body, the rear expansion structure increases the interior living area of the main body by 50 to 100 percent;
• and
• a second side expansion structure operable to extend from a second side of the main body, the second side expansion structure increasing the interior living area within the mobile living unit.

• one or more support arms disposed at a distal end, relative to the main body, of the first side expansion structure, when the first side expansion structure is in an expanded state, for supporting the first side expansion structure on a surface;
• and
• one or more rear support arms disposed at a distal end, relative to the main body, of the rear expansion structure, when the rear expansion structure is in an expanded state, to support the rear expansion structure on a surface.
