I suspect that the only cad files are those made by people who took detailed measurements of their own trailer and input the data to generate their own design ideas. The mothership isn't likely to release their drawings files (if they even use CAD drawings). I'm not sure how many members here have CAD software available to them. I'm an Architect and have the software, but even I haven't bothered creating drawing files.
