International Truck says orders are brisk so far for its new International HX Series vocational truck, announcing its largest one-time order to date.

RLJ Thompson Trucking, Inc., based in Concord, Va., has purchased 15 HX620 trucks equipped with the 15L Cummins ISX engine.

International Truck recently launched the HX Series, a new line of Class 8 premium vocational trucks and tractors designed for the severe-service industry and the first new vehicle introduced by International since 2010.

“We already have orders for more than 300 trucks and that number is growing by the day,” said Jeff Sass, senior vice president, Sales and Marketing, Navistar.

RLJ Thompson Trucking will use the HX620 dump trucks to meet customers' aggregate hauling needs throughout Virginia, Maryland, Washington, D.C., North Carolina and South Carolina.

“We ordered the new HX Series trucks because we are excited about the bold design that offers a sturdy, yet lightweight truck powered by the ISX engine,” said Ricky Thompson, president of RLJ Thompson Trucking. “As with previous International Truck purchases, we value our relationship and superior support service provided by our International dealer, Powell’s Truck and Equipment."
