I drive a Kenworth W900 with a Cummins X15 Engine and a 18 speed manual transmission. The heaviest load i carried was a big metal pipe, it went all the way to 200 ft! I got a lot of police escorts. My smallest load was when i had to haul a 28 ft reefer with 5 pounds of food. My most unique load was a 53 ft dry van trailer full of broken computer monitors. My funniest fail was when I was carrying a 53 ft reefer trailer full of pizza, the trailer doors opened and the pizza spilled everywhere!
