I wil be buying a 2006 durmax diesel truck soon. I like the idea/ ease of use with a fumoto valve for oil pan drain. I am assuming that 4x4 trucks have a skid plate to protect the pan. I will be getting a 4x2 which I know will not have a skid plate. The question is will the fumoto valve be protected enough on the under carriage of a 4x2. I will not be doing off roading just everyday driving/towing.
