I found the stud on the right side, I found a stud in the corner, I found a stud on the left side about halfway out from the corner the width of the cabinet. I wanted to support the end of the track at the rail for the bed on the left so I bought a thin sheet of sheet metal, actually a kickplate for the bottom of a home entry I riveted two pcs of sheet metal on the left ends of the track, removed one bolt holding the upper bed track, slid the sheet metal under the rail and shot the screw back in. This baby is solid. Just got back from 26 hours or driving to Bristol TN, to see the Outlaw sprints on the dirt at bristol motor speedway, The cabinet door is held by locking or by a magnet. The Magnet held fine. I could easily stack another cabinet on top with no issues.
