Slide a large piece of cardboard under the truck after driving for ten minutes note in which area directly above the spot on the cardboard the oil is coming from then get under the vehicle with a drop light to look for the origin of the leak, if no leak is detected then it may be the engine is burning oil this could either be valve stem seals or broke or worn oil rings.
