I saw a Tuff Truck competition once that started off with 50 yards of 2' washboards followed by offset washboard humps on a left hand curve, then a jump into a pond followed by a right hand turn with BIGGER offset washboards, then a BIG JUMP and a jump over a ditch on the home stretch to the finish line.
Ford's, Chevy's, Dodges, and Jeeps were bouncing all over the place and parts (windshields, tailgates, hoods, and fenders) were flying everywhere. Then here comes a stock Subaru Outback......Hammered through that course like a champ, not a single part went flying, and beat everybody's time by more than 8 seconds. 😄
