In 2010, Cobb announced that she would run full-time in the truck series, after purchasing the assets of the No. 10 truck team from Rick Crawford, whose Circle Bar Racing downsized from a two-truck operation to one — Crawford's own No. 14 (which would also close down early in the season). Cobb kept the same truck number and owner points from Circle Bar. Also that year, Cobb became the highest female points finisher in history in any of the three major NASCAR Series to that time, achieving 17th place.
