I don't have a clue how to go about doing a spread axle trailer Just don't know enough about big rig trailers. To build a "slab" sided trailer, wondering if I could take flat Evergreen sheet plastic and trace the sides of an AMT Coors or Kodak trailer onto it? Just don't like the old school moving trailer look of the original kits. For their time, they looked fine for a big rig trailer, just not a race trailer.
