Disappointed.  The instructions suggested using a drill to install but the kit does not include a hex bit.  The size of the hex bolt was either to big or too small for my own tools.  No size indicated.  The allen wrench provided was a piece of junk and rolled off the shoulders after the second bolt.  I hope I never have to relocate it anytime soon.  The centre braces did not line up properly with the holes.  The brace end in the middle of the bed is flush with the support rail BUT is almost 34 lower than the outside rail.   VERY frustrating putting this together!!!!
