This is what I did with mine, I mounted it on some 20x20 rhs steel to keep some space bwteen it and the tray floor so it can dry quicker when it rains and hopefully keep the rust at bay and then welded a rail on top of those at the back of the box, that way I can mount tiedown straps behind the toolbox so I have access to it without undoing straps all the time.
