Real life. Real tough.
"... In March of 2005 I flipped an F-350 on the beach in North Carolina, as many as 8 times. The WEATHER GUARD saddle box that was bolted into the truck tore itself out of the bed, and they found it somewhere on the beach. It was full of tools and weighed close to 1000 lbs. With the exception of damage to one side of the locking system, the box survived in good shape. WEATHER GUARD replaced the locks and the box is still in use today. "
