I cut out wood plates for the handle and the tip of the shovel to hold the shovel in place, those panels are screwed into the trailer wall. I drilled holes through the handle and shovel tip, through the trailer wall, ran a 1/4"x20 bolt through into a tee nut on the inside. I don't use the shovel often so I don't care that it takes a 7/16" wrench to remove the shovel. Besides, it's a theft deterrent.
