I tried doing that rolling ,dump the clutch ,thingy while I was employed by some Arkansaw hillbillies that own P.A.M.By shear luck, and happen stance,and five gallons of old motor oil with metal shavings, the old FDL with about half a billion miles on her,and shook so bad, that I could mix a perfect margarita while going across route 10 in LA. without being near a blender,was replaced by a brand new Century Class.While rolling up and over that E-ticket ride known as Sidling Pass, and armed, with what I thought to be, cutting edge knowledge of how to beat the man, and foil his feeble attempt at curtailing my thirst for maximum velocity,hurled myself and 85,000 pounds of steel and mostly plastic truck down the mountain until I reached a speed of around 95(i was told 75 would do but,I just didn't think that was an adequate speed)mph and while reaching for the freshly made margarita(Ok,that last parts a lie)I caught the sleeve of my coat on the shifter putting the truck into,oh,I dont know,5th gear maybe.The sound the transmission made as it went into both high and low sides was what a T-REX must have sounded like giving birth,very impressive.Shortly there after the arkansas hillbillies deemed i wasn't up to snuff or just out of my f#*!ing mind,seeing how some rat bastard JB Hunt driver told them how i did destroy their truck.Sorry about rattling on so,but i just had some coffee my sister sent me from Jamaica,damn stuffs like jet fuel.stay safe
