Rocky Mountain Great Dane (also known as S&P Brake Supply) has joined the full-service dealer network at Great Dane. Headquartered in Billings, Mont., the business has grown from a Trailmobile parts dealer to a full-line dealer for Trailmobile, Western Star Trucks and Heil Tankers. Today, the family-owned and operated dealership operates three service centers across multiple western states. Rocky Mountain Great Dane’s main facility in Billings now carries the entire line of Great Dane trailers and is the home of a 45,000-sq.ft. parts sales and service center with ten drive-through bays for truck and trailer repair.
