Please remember, even if you were the last one to drive the truck and everything seemed fine when you parked it, things can still happen overnight.
You may not have had any leaks showing on the ground when you shut it down, but that does not mean something did not develop afterward. A pinhole leak in a cylinder liner could leak coolant into the oil pan overnight. A hose may have been changed in the shop and coolant may not have been fully topped off afterward.
That is why proper pre-checks matter every day, even on equipment you drove the day before.
Please take the extra few minutes to properly check your equipment before heading out. It can save you from getting stranded and help prevent major damage.
Thank you and drive safe.
