Why would someone pay the price they are asking for these new trucks and not follow the instructions in the manual for break in?!?! I try to follow the break in procedure in the owners manual and that doesn't include hitting the expressway especially for an extended trip. I hear the same thing in recreational forums. "Drive it like you stole it" . Whatever. I've always gone with mfg recommendation on every engine I have owned and I have never had problems. Autos, ATV's, Sleds. This is exactly why I don't buy used equipment. You cant trust anybody to follow directions.
