have the same problem. showed loader operator where to place the load and asked he only load between 7 & 8,000 pounds as my trailer had a gvwr of only 14,000 lbs. he front loaded, so I asked him to add a little bit in the rear to lessen the tongue weight. when I crossed the scales, there was slightly over 18,000 pounds. my dump mechanism would not lift to dump the excess. had brand new 12 ply tires mounted and drove about 35 mph all the way home without incident. had to use the front end loader on the tractor (80 hp Massey Ferguson) to help lift the front to dump. on the next load, asked the loader operator to again only load about 7-8,000 lbs in the center. he did a little better and only loaded 14,000. the hydraulics still needed help from the tractor fel. I discussed it with the scale/ticket master and he said they weren't used to loading smaller trailers. I actually feel like its a passive/aggressive attitude of the individual operator in my case. he resents people trying to save a little money by hauling for themselves. dump truck operators here routinely charge twice the price of the materials or more per haul for a distance of less than 10 miles.
