Multiple use adjustable security trailer for transportation, storage and housing

A method for converting a trailer from a transportation mode into a storage/housing mode, said trailer having a frame;

• a substantially Y-shaped tongue having a pair of side arms pivotably mounted to each side of the frame and a front tow bar with forward hitch means;
• a pair of flip-down legs each leg being affixed laterally to the frame by pivot means and a hitch pin inserted through a flip-down leg hitch means;
• a foot plate;
• and a vertical hitch means at an upper portion of the side arm and adapted to be connected to a tow vehicle, said method comprising the steps of:
• disconnecting the front tow bar with the forward hitch means from the tow vehicle;
• removing the hitch pin from the flip-down leg hitch means, enabling the flip-down leg to pivot downward about the pivot means into a substantially vertical position thereby contacting a ground surface and vertically supporting the frame;
• pivoting the front tow bar of the tongue upward and pivoting lower portions of the side arms of the tongue downward about a pivot means into a substantially vertical position;
• pivoting the tongue into a substantially vertical position perpendicular to the frame about the pivot means, thereby engaging the lower portions of the side arms as support legs and vertically supporting the frame;
• and
• securing the side arms of the tongue in the substantially vertical position by inserting the hitch pin into the vertical hitch means.
