Ultimate ATV Rack

[Rax]

Im looking for a set of CAD prints for the ultimate ATV rack. The ultimate rack is a system for hauling two four wheelers on the bed of a pick-up. I can design my own plans but I need to know the tubing size and thickness or angle iron size and thickness. Im also seeking info on trailer building like axel offsets perferably a tandem or triple set up.

Thanks
