You guys are cracking me up. Can't believe Doc Tinker hasn't found this thread yet.
Haven't hauled anything that nasty smelling but I did haul a load of broken up drywall that tore up the paint on my Ford truck real good.
Stinkiest experience for me was when I was a foreman in the special services group of an electrical contractor, I had to install and hookup a control panel in the pump house of a sewage plant behind a hog slaughterhouse in North Carolina. Two of my men quit, the other two toughed it out. One kept puking, the other one was pale all the time. I ended up using my earplugs as nose plugs, but man, after awhile, it felt like I was tasting pig excrement, just from having to breath through my mouth. We got that part of the job done in 3 days. I lost about 10 lbs. from not being able to eat.
I got stuck behind one of them carcass trucks like Mack 96 is talking about, on my way home from Muncie one time, I was ready to shoot out the tires after 2 miles of following him and being unable to pass !
