I used to have a 16' PJ low profile gooseneck dump but I sold it this week. It hauled my skid steer or backhoe just fine. I sold it because we bought a dump truck. It was a great trailer and ideal for a property owner because it is so versatile. I hauled dirt, gravel, tree branches, equipment, building materials, etc.
The dump truck was a better fit for us because we do hauling of dirt and gravel for people and the trailer was hard to get into some of the places we have to dump and it required two trips to move the material and machines to a jobsite. Now I make one trip with the dump truck and a pintle trailer.
