You know it V.B. They're brand new and for some reason, they haven't governed the engines yet. Went through the radar they have set up before a long hill doing 47kmh empty and 43kmh loaded(234 tons). A mans gotta know his limitations. The 200 ton trucks only do 35 but the hot rods(150 tons) do 67!! Two years ago, buddy called me on the radio and told me that my truck was the first one he'd ever seen get all four wheels in the air.
