I crawled under my truck the other day to change the oil for the first time and noticed the oil pan seems to be the lowest thing on the underside of the vehicle (least ground clearance) and DC did not equip the truck with a rock guard. My truck is a two wheel drive, just wondered if there is a company that makes a rock guard to protect the oil pan? I live across a 40 ft. wide creek and sometimes it gets badly rutted, sometimes big rocks are washed down onto the crossing... I'd hate to lose an oil pan or an engine!
