Transcraft and Benson products will be stocked and sold at authorized locations in both Dallas and San Antonio.

We’re excited about the possibilities for both businesses, as well as our mutual customers,” explained Chief Executive Officer Dick Giromini.

Summit Truck Group will be fully stocked with new model year Wabash National van trailers, truck bodies, and Transcraft and Benson platform trailers, in addition to being supplied with a full selection of parts.
