John King has the points lead going Into this weekend’s NASCAR Camping World Truck Series Kroger 250 at Martinsville Speedway. After winning the NextEra Energy Resources 250 at Daytona International Speedway, King will have his work cut out on the, often wild, half mile paper clip that is Martinsville Speedway. Making the change from the large super speedway of Daytona to the short track set-up isn’t always easy. Brake and equipment wear may also come into play. Drivers who can take care of their equipment to make it to the end have a chance to take the checkered flag. Martinsville is known for a lot of contact. With a confined space for pit road and a half mile track, there will be plenty of carnage.  Timothy Peters and Justin Lofton are 2nd and 3rd in the standings and will also be looking for strong runs to stay on top of the standings.
