Can't agree more. We are building a house and yesterday my wife and I went about 45 miles north to get some brick and chimney block to build the chimney with. I took my brother in laws 16 foot trailer to haul it on. After they loaded the 2 pallets of brick I asked the guy about what they weigh and he said 3500 pounds a peice. Then they loaded the 33 flu block and 11 flu liners and 1000 pounds of mortor. I skipped on the sand for now lol. That put about 11,000 pounds on the trailer itself! I was starting to wonder if the trailer was going to handle it. I put 45 pounds of air in the trailer tires before I left and off we go. Thank goodness for the 6 speed or I would have burnt my brakes off. Had to play with the clutch to get took off but after that the truck pulled it pretty good. Figure in about 1k pounds for empty trailer weight and the ol 05 double cab had about 12k pounds behind her. Not bad I say. I love my truck
Thankfully you live several states away, as the idea of such an overloaded vehicle on public roads reminds me of a tornado warning; in both cases you never know where it will strike.
The reason for a load rating is to keep you from either killing yourself, or innocent bystanders, as the brakes, suspension components, and frame of the vehicle can only take a limited amount of force.
If you are lucky and can handle that amount of mass over a long period of time, then the forces will be within the limits.
If you need to turn or stop quickly, that 13K lb. load will twist your frame, boil your brake pads and fluids, and snap suspension components right off.
Take a look at the carnage from just crawling empty rigs.
I'd hate to see anyone get a 13,000 lb. enema.
