Penner International 
Penner specializes in U.S.-Canada truckload movements in western Canada (Winnipeg to Vancouver) and the American Mid-West and to Toronto. They use five-axle tractor-semitrailer equipment that largely comply with U.S. Federal regulations, although they use heavier tractors than their U.S. competition, 20,000 pounds versus 17,500 pounds. They also use heavier trailers with I-beams at 18-inch versus 24-inch spacing. Their tractors are equipped with air-slide fifth wheels at an added weight of about 200 pounds. To further facilitate load distribution, all trailers are equipped with moveable tandems for an additional weight of 350 pounds per trailer. These devices provide added flexibility in loading. In practice, many drivers like to “stretch” their vehicles, sometimes leading to overweight axles. Penner believes that large U.S. fleets do not use slider equipment to the extent used in Canada to save tare weight and additional expense.
Penner is assessing its specifications which led to heavier tare weights because of increasing competition on payloads being offered to shippers by U.S. carriers. Penner's standard payload has been 44,000 pounds. At 80,000 pounds GVW, this allows a tare weight of up to 36,000 pounds. Certain competitors are offering payloads of 47,000 pounds with an 80,000-pound cap for the same mileage rate.
One-half of Penner's trailer fleet are 53-foot semitrailers, and the other half 48-foot. All new semitrailers in the past two years have been 53 footers. About two-thirds of Penner's activity cubes-out, while the remainder weighs-out.
Penner often routes traffic running between Winnipeg and Toronto across U.S. Route 2. This route is 40 miles shorter in distance and has lower fuel prices. Several other Canadian carriers also use this route.
Kindersley Transport 
Canadian truckload carriers operating into the United States typically use heavier power than their U.S. counterparts (for example, a Detroit Diesel engine at 380-400 horsepower versus a Cummins M-11 at 330-370 horsepower) and similarly heavier transmissions. One reason for this is that the equipment must also be employed in heavier Canadian haul operations. As such, Kindersley's typical Canadian tractor would have a tare weight of about 19,500 pounds versus its U.S. equivalent of 17,500-18,500 pounds. Because the Canadian tractor is heavier and often employs a steering axle set-back about 18 inches, most of this weight difference, 1,000 to 1,500 pounds, is applied through the front steering axle.
Kindersley reports increasing traffic from western Canada into southern California in terms of truckloads of paper and newsprint, chemicals, and peat moss. When in season, produce is returned northbound to destinations throughout western Canada, requiring the use of temperature-controlled equipment.
