I seriously doubt that road can get any rougher and still be classified as a road. I came across there today with an 8,000lb load. Traffic wasn't too bad at all. Couldn't do anywhere the 45mph speed limit not because of traffic but because when I approached that speed, I could barely keep the truck going where it was supposed to go. I have in all honesty driven on 1 lane dirt (not gravel) roads in WV that hadn't been touched by the state in years that are smoother.
But, if you're trying to find out what all is lose on your truck, that's a great place to do it. Just hang on, though.
