Looking into this a little farther, my truck is registered for 9,000#. My chipper and sawmill both weigh about 3,000#, so that falls well below the 17,000 limit. However my dump trailer and equipment trailer are registered for 10,000#. So according to what you are saying whenever I haul my dump trailer, regardless of if it is loaded or empty, I should have DOT numbers? Its just a 2500 pick up, I added bumper stops on the springs so it doesn't sag even when its fully loaded with chips and the chipper. If you don't look like you are grossly overweight and don't throw any red flags, I always felt like they wouldn't bother you. It sounds like a royal pain in the ass to go through what you're going through to get the DOT numbers.
