Established in 1981, Dunlop Truck Centres (formerly Rocky Mountain Diesel Ltd.) is a rapidly growing dealer of Western Star and Cummins engines. Dunlop also offers service on Detroit Diesel engines and all major truck engine brands – along with an impressive supply of heavy truck parts. It has a separate collision repair facility at its location in Cranbrook. Since 2008, when current ownership took over, the company has quadrupled its revenue growth. An excellent track record of customer service and company culture have contributed to Dunlop’s success.
