I've actually been toying around a little the past week with the idea of building a dual-axle hauler. Since I have several empty chassis sitting around, I could just attach the back half of one onto another....basically like a mini-tractor/trailer. I don't think it would be necessary (or feasible) to round up dually rearends, but with a little tweaking it would almost look like a miniature big-rig, and definitely be something unique.
