I want to build an under bed gun case. It needs to fit under a full size bed and can replace the frame. It can be double height what the normal space is under the bed and should fill the entire space under the full sized bed. It will need to be able to drop one side open and slide a large drawer out from under the bed. Anyone have any such plans or know where I could find some? I'm interested in something like one of these pics. Maybe 2 or 3 drawers that slide out from under one side of the bed. Will need to lock.
