In ohio here is how it was explained to me. My truck is a 5500 GMC with a gvw rating of 19000. Unloaded weight is 8700. My trailer is rated at 14000, empty it weights 2500. I have used F350 and simular hd pickups over the years and they just do not provide enough braking abililty, even with bakes on all 4 wheels on trailer. My little dozer weighs 10,000, fully loaded, truck 8700 trailer 2500 dozer 10000. a total of 19,500lbs. I went through a weigh check point (dozer was not on trailer). My combined weight was 95000 across the scale. They pulled me in and give me a tilcket which cost $150. He said my truck was rated at 19000 and my trailer was rated at 14000 which could put me over CDL if fully loaded. My truck would not pull 33000 lbs I tried to explain and would be right back where I started from a truck with not enough braking ability, making it unsafe in a sudden stop. He could care less about safety. I didnt have a cdl so he made me unhook my trailer and leave it. I went home and got my little Ford ranger, and it just fried his but when I showed up to get my trailer. Totaly legal (but not safe) . No wonder truckers hate the puco. You cannot reason with them.
