Use large head cabinet or similar screws thru the cabinet frame (top and bottom) into the vertical columns of the trailer walls. If you are starting from new also position your horizontal laths to match your cabinet dimensions. Pre-drill a pilot hole, then screw all they way thru to the verticals. Obviously check your screw length to make sure you don't go all the way through.
If your trailer is aluminum, try to use a stainless or plated screw to minimize corrosion.
