Thanks for the correction. I will make the partnumber change.
The complete Andy Mark Payload AM-0313 trailer has just been posted. I removed all internal brackets so that the model file size would be smaller. The 3d preview image only shows the bumper. The 2d preview shows top, front, right and isometric views - but the model file downloads fine in all 3d and 2d formats.

If you are using SolidWorks, use mass properties in the assembly to add the weight of your trailer. AM should have that value. Also, use a Tangent mate on the wheels to the slick floor surface and a Concentric mate to the hole of the trailer channel bar where you put the pin to connect to the robot. That way you will see the rotation (swing) the trailer will have. Marie
