I have a 2005 Haulmark 6x12 white enclosed trailer with ramp door and side door. It has the 6" extra heighth and diamond plate nose as well. I'm thinking about selling it and buying a open trailer. We do hardscaping and mowing and just feel like a larger open trailer may be better for our operation. I have no idea what it's worth just wanted to see what someone else thought and possibly sell or trade it.
